I just got some great textures from 3dtotal.com that came with bump maps. How do I apply the bump map in Bryce?

The bump map goes as a seperate picture texture. You have to have it in the middle slot on the screen where you edit picture mats. Then, back in the texture editor, just be sure that the little dot for bump height is clicked on the channel where you have the bump map loaded. Make sense?

I think you lost me. :-(

screen shots really help with the material lab. I still don't understand it well myself. For some reason I was thinking that the bump came from the 3rd slot. Shows what I know. :) Sorry I can't be of any help. Ang

Well as per usual I was in the wrong place in my mind. Silly me. One thing though and correct me if I'm wrong but shouldn't there be a pebble on the bump height so that the bump map is utilized?

Yep, Ang, you're right: there should be. Without it, the alpha won't drive the bump.

And you have to pull out the slider thingy...

I would have done screen shots but I was in a hurry :)

BTW in case some people don't know. Using the bump slider only goes up to 100 but if you type the value in (by clicking on the value nuber) you can get it to 999.

rofl...yeah having a bead in the bump channel will help a LOT...;o) AS

Aldaron; higher setting then 100? wich version of bryce do you use? Last time I succeeded in 'overloading' channels with settings higher then 100 was back with B3.

I've used B4 & B5 with a setting higher than 100, with the bump channel only. AS

Me too, Rayraz (B5), after good ole AgentS revealed this to me. In many of the images in my gallery in which I used phototextures I used bump settings between 200/300.

That's new to me. I've tried it on the diffusion and specular channels and it didn't work, so I assumed it didn't work at all. Using settings higher then 100 was one of my favourite trics to use on textures back when I used B3.

Yeah it only works with the bump channel.

So what does having a number higher than 100 do to the image? I didn't know this and never even thought of trying a higher number. Catlin

Having a number higher than 100 makes the bumps larger 8-P I figured this out couple of months ago, and that put to rest my curiosity about if Bryce actually put the bumps on the object or just simulated them. A setting of 999 causes shadows extreme enough that you should be able to see the bumps from a side view, but you can't. I don't recommend using it past 400 or so.

Yeah, all depends on the bump but only a couple times have I really used a 900 bump, mostly on fine, subtle line bumps, etc. AS

Do you mean that with it set to 900 that you can actually see the bumps stand out from the object? If so that is sooooo cool.............8) Catlin

No, unfortunatly not. The reason I suggested no more than about 400 was because you can't see the bumps stand out, and it looks very odd with the shadows that are getting projected from bumps you can't see.

Bumps that stand out at the edges are a result of displacement mapping, not bump mapping. Which Bryce don't do. I find I get best results in Bryce with quite small strengths ( < 10 ) and setting strengths of 50 or 100 doesn't really seem to have very much more effect, which makes me think there is a saturation point in the bump mapping algorithm quite low down the scale. Last point: many image textures auto-bump very effectively, which means you load them in at the left and do copy/paste to get the bump map in the centre window.

They're right, the large sectional bumps are made from metaballs, they are not a result of a bump map, sorry for the misunderstanding. I was just trying to show something with a setting of 900 bump, which in this case would affect the small "cell" shapes that run across the surface of the rubber. Almost all bumps I use are around 25 and don't go above 50, and there are only a rare few that I would use 900 high. And, like Phantast said, most image textures will copy/paste and also work as a bump pretty well most of the time. Which if you can do it that way, it will help cut down on your .br scene file size (somewhat). AS

Thanks for the tips guys, but wouldn't it be great if the bump maps could give you a 3D look in the shadows. There must be some mathematical formula for that kind of thing. Anyway back to Brycing..............8) Catlin

Bumpmaps that actually change the object are called displacement maps. Instead of bumpmapping it's called displacement mapping. Bryce doesn't have a feature build in for displacement mapping on anything but terrains and lattices. Many other programs do support it, but bryce doesn't. I did however once see a link way back when Bryce 5 was still under construction that claimed that B5 was going to have Displacement mapping along with a couple of other things as well like motion-blurr. I never bookmarked the site unfortunately and I can't find it anymore. If the site told the truth there may still be some coding for it hidden in Bryce, but it's probably not usable.

Ah! that must have been in the starry eyed days Rayraz before we came to know the true horrors of Corel. Catlin

Not to change the subject but...on a different subject; From reading between the lines in boringly long press releases about Vector Capitol & Corel, it seems (SEEMS, mind you) like Corel won't be dissasembled or anything. Seems like Vector will just control Corel to make it a profitable company. So, maybe the name/company Corel & its products will not "go away". Still, that is just a guess, and it still says nothing about Bryce. sigh... AS

AgentSmith, I'm going to post an image entitled "Death of Bryce". Now I'm telling you this so you don't delete the message before you have inspected my handywork. 8) Catlin

oooookay......
