Bryce F.A.Q (Last Updated: 2024 Nov 26 4:28 pm)
I'm not sure what you mean that maps only look right from the front. Perhaps you could upload an image for us to see the problem. Bryce doesn't do displacement maps like some other apps. You can create your own bump maps and load them in the texture editor. You can also switch the texture mapping mode from the drop down list in the materials lab to suit the object better.
i'm sorry i dont have a connection at home so I'll have to wait until next weekend before i can upload an image. Let me give an example of what I mean. If i put a bump map on a box the bump will show on the front of the box, but the sides of the box come out smooth. Beeing norwegian I hope I have been able to explain this in english. I know how to create a texture.
Image TWO.. is what you get as a result...
click the check mark to get back to the Materials Lab....

Hope this very quick tut helps out...

Displacement is a tool that actually tessellates the geometric surface itself, not merely drawing an impressions as with bump. Displacement actually add real polygons to a surface normal.
That said, Bryce does not have displacement abilities, not yet anyway. Let us see what hap;pens with Bryce 7. seems they are getting a lot of things just right with the new Beta!
Basically, a bump map interacts with light sources to paint a picture of a shadow on a surface, thus giving the illusion of bumpiness. Depending on the angle of the surface and the light source(s), the shadow pictures can become inaccurate. For instance, on Poser figures, it's cool to use a displacement map to subtly simulate veins on the surface of the skin. The mesh is actually pulled by a displacement map. But use that same map as a bump map in Bryce and one side of the figure will have veins, but the other side will probably have a negative effect and it'll look like someone gouged out little trenches in their skin! You can work around this problem somewhat by reversing the value of the bump on the side that's incorrect, but again, you're just playing with artificial shadows.
Displacement is probably the number one thing on my wish list for Bryce. I heard from someone, unofficially, that Bryce 7 will eventually have displacement.

It is Tom an a 2d scale if you will, true displacement actually alters the shape of the object here's a link to what I mean. http://www.evermotion.org/tutorials/show/7937/fryrender-1-8-beta-reviewDo atleast one thing a day that scares the hell outta ya!!

Bump maps only look right from the front. Is there a way in the texture editor to do displacement maps?
