Subject: IDL and objects with reflection


Winterclaw ( ) posted Mon, 22 April 2013 at 12:01 AM · edited Sun, 22 December 2024 at 9:51 AM

Okay, I have this easter bunny box that was very shiney and reflective (IRL of course).  I happened to notice it did a very good job of bouncing its color onto other objects.  Since I noticed it, someone used to looking for these things would probably be like, whoa. 

 

Is this something poser can do.  I'm playing around with reflections and IDL now, but it seems that even with extra bounces, the other surfaces aren't picking up any reflected color.

WARK!

Am I missing something here? One statement seems to contradict the other.

Indirect diffuse light will not pick up any specular reflections.

Poser still doesn't do caustics (I'm assuming this is what you're refering to), which is odd because Smith Micro made a valiant attempt at ramming every other cg advance that's been around for a while into Poser 9. Guess they couldn't shoehorn caustics admidst SSS and WM'ing and GC.

WC's not talking about caustics....WC's talking about light color transmission (how a colored glass imparts its color to the light that comes out the other side such as a stained glass window will shine colors on a wall rather than just the outline in white light), which Poser can only "fake" with a gather node but can't do natively....kinda like it can't do caustics. LOL. If you're not talking about either of those WC I have no idea what ya mean. LOL

Sounds like a shiny foil box, e.g. a red foil box reflecting red onto a white wall. Is that transmission or caustics or something else? Winterclaw, we demand to see the Bunny Box. In fact I want one, preferably with a chocolate bunny inside and a solid one, not that cheap hollow kind.

Ok, turn on IDL.  Make a blue or pink or whatever object using the diffuse channel.  Put it right next to a white one.  Render.  The white object will have some blue or pink on it.  Instead of diffuse, use reflection.  No pink or blue will show up on the white object.

WARK!

Hmm....that kinda sucks. LOL. There's just some things Poser doesn't do tho and we all gotta live with it or render in something else....hehehe. A lot of people do that infact ;). Luxrender or Blender Cycles or Vue or Bryce. :). I have my own issues with that, but I just use Luxrender then and problem solved ;).

Content Advisory! This message contains nudity

perhaps OP means something like this.   bounced reflections aren't done by IDL, however IDL is needed for emitters in scene.

Winterclaw ( ) posted Sat, 27 April 2013 at 4:49 PM

I think I figured out the problem: it might be the order of operations.  If IDL is applied before reflections, and I think that it is, then whatever color the reflective object has won't bounce.

I am trying to recreate the effect that Andrew Price got when he created the Earth in Blender. I downloaded all his texture, bump and trans maps, went to work in Poser, and 9 hours later I gave up. I just couldn't do it. The other thing I wanted to create was the effect of when the planet is rotating in the animation, how you could see the dark side with the city lights and the light side as normal, and it changed with the "sun" hitting it. Couldn't do that either. He used a color ramp, and when I attempted it, I couldn't do it.

The material room is still kicking my butt.

Miss Nancy ( ) posted Sun, 28 April 2013 at 5:26 PM

whilst I dunno how to apply reflections and IDL in some order, other than to do two renders, perhaps rokket could post poser render of earth, along with render settings.  I looked at AP's tute for ~30 sec., but didn't see any city lights.

p.s. it's common misconception that girls with implants can use them as flotation devices, given that both silicone and saline bags sink.



primorge ( ) posted Sun, 28 April 2013 at 5:41 PM

...That would explain all of those silicone and saline bags at the the bottom of my pool! :)


lmckenzie ( ) posted Sun, 28 April 2013 at 5:44 PM

That liquid looks pretty dense. My guess is she'd float, though whether they would keep her head up - ala the eponymous 'Mae West' is another story. If she's equipped with those notorious Fix-A-Flat butt implants as well, the fluid sim would be fascinating. At any rate, cool fan service.

I deleted the scene, so I would have to start over with it. But I could put something up in a day or two. In the meantime, here are the two maps he used for night and day. Of course, I combined them into one pic and resized that for the forum. The originals were 12000 x 8000 pixels.

o.k., I got this, but needs work.  it's mesh lite problem - poser inf lite don't generate terminator.  didn't view tutorial, but I can see why those blender guys were getting square artifacts.

That looks so much better than what I was able to achieve. Can you open the nodes so I can get a good look at the settings? I know what each node is, except for the one labeled "Tile", and I would like to see the image maps.

Here is what I was able to do. I added in the clouds, but they cover up too much of the planet. Everything I did with transparencies and the trans maps didn't help.

I deleted all the lights except for the IBL. I am thinking that I can create a map for the IBL of space with the sun at the far left, maybe that would do the trick. I also rendered one version of it without IDL, and it seemed to work better, as I wasn't picking up light from the whole model.

rokket ( ) posted Mon, 29 April 2013 at 9:36 AM

This was only the second step. The finished image I deleted was rendered on a black background, and while it looked cool, it didn't look very realistic. And realistic was what I was going for.

Here is my settings for the planet. I really need to learn more about nodes, I can see that now.

here's one with nodes. in fairness to OP, postpone any further discussion until he posts render of his reflection/IDL problem.

blender guy's earth maps in poser

better method requires svl. math nodes to account for diffuse illum. from mesh lite IMVHO. skip clouds for now, make sure earth is lite emitter, invert spec mask, et al.

Sure, I don't want to hijack the thread any longer.

Thanks. I will work on this some more. Maybe start my own thread.
