I have an imfitie light showing through the stained glass. But I'm getting white light on the floor. How do I get the window colors on the floor?

Thaat's caustics and ATM poser can't do those. It looks like Poser 11 will, if you cam wait and afford the upgrade. Otherwise, you'll have to fake them. One thread for this is here http://www.renderosity.com/mod/forumpro/?thread_id=2695748& Look at what bagginsbill said.

haven't seen that one - goes back to P7. thx fr link, red.  nerd said P11 has caustics, however stain glass problem may be light thru transparency, which nerd ain't mentioned but which stefan may have added.  OP can also fake that with blurred map on spotlite at xtreme distance, narrow beam.

it might also work with translucence.  lite has map but window is white diffuse backface with translucence<=1.

 spotlite may produce coloured atmospherics (god-rays).

And when is Poser 11 supposed to come out? I hope it works better that 10 and 2014 did.

All right then. I have Vue 2014. Maybe I can get it and get it to work in that.

 thx to OP fr question.  helps me realise how they may have set up area lites in P11.  much better than P10 diffuse emitters if I'm right.

Try a one sided square and the windows image map one the floor.  Mask out all but the colored panes, adjust the transparency and translucence of the material.  Also experiment with light emitters on the panes. 

You can also post work the caustics.

I just broke down and took the render into photoshop.

I do appreciate everyone's help, though.

try again:

am tempted to post one in new gallery (they wiped our imgs) labelled "area lite in P10"

oops! it reversed posting time!

it looks great! here's one w/translucent disc in poser:

oops! can't post img w/new forum software

wait, I was wrong! they didn't wipe all galleries
plus they now gimme over an hour to edit this

I put the window map on the single infinite light. Had to play with the tile UV proportions and offset until the projected map matched the cast illumination and also enabled atmosphere volume.

I will definately try that. I forgot about applying textures to the lights.

Connatic, I'm confused. I can get the texture on the light, but I have to make it a spotlight, shrink the size of the light and practically out it on the floor to get anything close to what we're trying for. What did you mean by UV proportions and off-set? Those are things I have never dealt with.

Here is a capture of the infinite light materials pane. This was an experiment for me, trying to achieve what you posted about. I had never added an image map to an infinite light other than hdr/environment types. At default with the image applied it projected multiple tiled versions. So, I decided to try changing the U and V scale and offset values, and it eventually gave me the expected result.

I see what you're talking about now. I'll try again and see what I can do. Thanks for helping.

The values in Atmosphere materials Are:
Volume On
Vol_Color = white
density= .025
stepsize= .8333

When I made the render I had unknowingly left Ambient Occlusion On for the light and it was set to .7.....The rays are still visible with it set OFF, but are somewhat less intense. The render speed without AO is much quicker. Also the light atmosphere strength = .01

Got it. Thanks.

My render has a lot of bizarre artifacts from the atmosphere. The building probably needs to be very tight at the seams to eliminate that. Possibly doing several versions of the render with various settings/combinations and then compositing as layers could get rid of the noise. Much more experimenting is needed!

I think we're all writing the book as we go on this.

Connatic, I used the exact same numbers you did. I guess it doesn't work in Poser 9.

The UV scaling was relative to the size of the window in my scene. Increasing the scale made the tiled image larger, until it matched the size of the opening. Also, you do not have shadows checked. I think that might make a huge difference. I suggest experimenting without the atmosphere being active, to get the image projection to align.

okay.

OKay. I started with 3. I'm up to 16 and the image is still all over the model.

Is the half-circle with the design a window in a wall of a building? In my render the projection is the same map which is used for a stain-glass window which is the only opening in an otherwise solid wall. The window is still a mesh with transparency. Your room looks like it has a lot more light shining, even in the stage display. In mine the non-rendered stage is very dark, no light on the opposite side of the objects facing away from the single active infinite light.

That half circle window is at the other end of the building. This is what I'm trying for- again, this was done in photoshop.

I am guessing it's something about the different buildings. I have no idea why the image would be cast where direct light should not be shining.

Ok then, I'll just have to stay with Photoshop then. I do appreciate you trying to help though.

What building are you using for your render, mdbruffy?

If I know what it is, perhaps I can download it and give this a try. Poser 9 and 10 both have the same basic firefly render settings (IDL, et al). I have both Poser 9 and 10 on my laptop. I can try this in both.

rokket, I made the building for my up-coming graphic novel. It's a free download at my Deviantart gallery:

http://mdbruffy.deviantart.com/art/Collected-Starfleet-Memorial-Gardens-554247993

Ok, cool. I will download it and see what I can come up with.

Okay- and thanks.

I tried several things but nothing really worked. But here are some things I learned from the pz2:

1. Your render settings don't include using IDL and they should. Getting any image at all to shine of the ground as if it was coming through the window was very hard to do with all those infinite lights you had in the scene.
2. The window that you want doesn't have a useable UV map to attach to the light. I would remap it so that you can use the image to attach to the light. OR
3. Create a .png image of that window, but place the light just inside and pointing down at the floor and attach the image that way.
   I hope this helps.

Okay. Thanks.

inf lite not good for this. use spotlite. if nobody can set it up in P8/9/10, let me know. steep angle of lite not ideal. in PBR (P11), it might be more interesting, if you can get betazoids to render this for you. I asked one of 'em but "mum's the word" so far.

Miss Nancy, the problem- on top of what we've been dealing with- is that this is for a graphic novel. Some pages would have as many as 6 renders on a page. I tried a spotlight and couldn't get it to work either.
I think we're out of luck on this until SM pulls something out of their hat.

One thing I would try is to take out the window and replace it with a blank. Then use texture and bump maps to mimic what you modeled. That would give you a better result.

But then when I show that wall with the light coming through, there'd be nothing there except a hole in the wall.

No, you're misunderstanding what I am telling you. You model the window but not all of the internal parts. In essence, you would have a disc up there, and the stained glass would all be texture map and bump maps.
Like this: Here is the Hi-res ball

Hi-Res ball with texture and bump maps. None of the globe was modeled into the ball. It's a blank.

Miss Nancy, which light? I'm not clear on what you're showing me.

That is a spot light.

Okay. I'll try it again. First time I couldn't get it to work.

I tried it with the exact same settings and got the same tiling effect I got before- the pattern was all over the walls. I have tried 5 tgimes now to load the image and the site will not respond and let me.I finally got it.

I believe you are attaching the image to an infinite light, not to a spot light.

Or you have the spot light too high in the scene.

There has to be some other factor causing the light to shine on the wrong sides of the walls. Although the spotlight is undoubtedly a better choice than the infinite light, I was still able to get the texture to shine properly with an infinite light. How is that texture being tiled on the far wall? If the lightsource with the map is outside, it should not be there.

It's splashed all over the set. Thing is, you can see where the light from the spotlight hits the floor- That's exactly where I want it.
Note to Miss Nancy: If I send you my e-mail in a private message, could you send me a copy of your scene file? If I compare EVERY setting, I might be able to figure this out.

If you don't want the image tiled, why do you have the Image_Mapped value set to Tile?

I've waited several days to see if anybody would notice that.

Miss Nancy had her settings set to Tile and I set mine exactly to match.
Just tried with Alpha, None and clamped and got the same result.

There are details within details within details here.

If you're

• using a spotlight
• have your image map scale set to 1 in both dimensions

Then the tiling does not apply and doesn't matter what you set it to.

If however, you're trying to scale the image to less than 1 in either dimension, then the Tile parameter value does matter and will reveal a difference.

If you're doing this with an infinite, not a spotlight, then it can only tile, and ignores the image if you use anything but tile, and will show many copies across the entire "world". (As tested in in Poser Pro 2014 - not sure if this is a recent change or not)

pz3 file (2.9 MB) won't work due on yer machine due to having 3 refs to my drive names, however I'll see if I can change it to be generic for P9.
had to extract window prop from yer scene due to large obj size (147 MB), so I could handle it quickly.
first, generate img map for spotlite using render of window surrounded by black, which I already did and can give you.
spotlite has angular falloff - compensate by large black border in img map.
window can be done many ways. one is to use fastscatter on white disk, as done in first image of spotlite with tiled img projection.
however that method requires UV-scaling at steep spotlite angle.
it's easier to just assign ambient = 1 to all colours in window, then turn off shadow-casting for window, then position spotlite with these parameters:
point at window (assuming window is facing front cam)
poser native units in prefs
angle 18
rgb 1
intensity 200
xtran 0
ytran 8
ztran 4
use img map below for spotlite
use matl room settings for spotlite as shown above
in P11 I daresay they will use something like how carrara handled stained glass.
tiling variable affects inf lite, but don't use inf lite

forum software won't allow me to attach img using markdown if there are space separators.

p.s. @BB: thx fr tip on spotlite. was gonna read manual someday! knew there was some way to adjust, but I recalled falloff graphs for some reason.
hey wait a tic! they deleted "mention" button, which everybody hated. next they should add "thank" button, like at rdna. those guys just updated
their software so now "thank" button appears in my browser (safari 5). now if I can just find "ignore" button at rdna to handle trolls there.
