Bump and normal maps

by Dave · in Torque Game Engine Advanced · 10/17/2006 (6:30 am) · 6 replies

Hi,

It seems to me that bump maps (greyscale) aren't supported in materials but normal maps are. That means the bumpTex param in a material is really a normalTex param. Is that correct or have I missed something? If there is a way of using plain old bumpmaps I'd love to know it.

Thanks,

Dave.

TSE supports the use of bump maps trough normal maps, yes.
bumpTex could be normalTex, if you wish :)

Heh, thanks Stefan. After posting this I found the GIMP plugin to make normal maps from 2D art. That makes making *some* normal maps as easy as greyscale bump maps :-)

BTW, the rendered model with normal map looks great in MAX but crap in game. As though the normal map is just sprayed on as a 2D texture. Any ideas on that?

Thanks,

Dave.

Aye, are you using the latest HEAD, or MS 3, 3.5 etc? I have not been able to get my normal maps working correctly in the latest version.

Yep, latest HEAD. That could be the prob then. Did you report it as a bug?

Yup :) The believed it was my GPU having 64 megabytes of RAM, which is not the case. I think someone is taking a look. The thread can be found here. Could be related.

Aha! Thanks. Seems possible they might be related. I'll keep an eye on that thread and see how it pans out.
