Bump Map Sizes

[JHuman]

How would I go about changing the size / scale of the bump map in VR4SU? The map works how I want it to, for the most part, but always comes out really really small.

Thanks!

hi.
check the material-editor. go into the bumpmap und underneath the picture you've got the intesity.... thats the one to play with.
hope thats what you've looking for

Re: Bump Map Sizes

To adjust the size/scale/porportions of any map use the "repeat" parameter under "UVW transform". It's a little counterintuitive as the higher the number the smaller the scale, so "2" will give you half the scale of "1" as the map is repeated twice over the same distance. For very large bumped textures (like exterior rippled water) you may need to use a repeat parameter of 0.001 to make it big enough.

Thanks for the comments, I gave those a shot, nothing seems work. I opened up a new model and just testing these out on some basic shapes, no bump, I can get displacment to work fine but bump dosnt work. Any other advice. I will give these a couple more shots. Thanks!

Re: Bump Map Sizes

You are using a texture aren't you rather than just solid colour? You need an actual diffuse map (even a solid white one) in SU's material editor to make SU give VfSU the UV coordinates to correctly assign a bump map.

In most cases I will have a colored wall then add the plaster bump I created, same with tiles, stone, etc. It usually works when you zoom in, its just a matter of trying to figure out how to scale it up. Although it never seems to be consistent from model to model.

Re: Bump Map Sizes

Why don't you put another diffuse layer, put the bump map there, and after you yo get the correct size in SU, make the bump map full transparent. You will get so called "ghost diffuse"

Jackson, you’re a genius! It worked. Thanks for the tips everyone.
