Render To Texture and colormapping?

[skogskalle]

Working on a realtime-project at the moment...

The realtime software (TurnTool) doesnt work with Vray materials... only standards. But I figure If I can set up my scene using Vray mats and Vray lights, then bake the light using Render to texture, then I could create standard materials with the rendered texture as diffuse... and everyhitng should in theory look really nice

heres the problem - I usually use some kind of colormapping when I light my scenes. But when I use Render to texture the texture gets really blown out...
I used the "exponential" colormapping method. is this not compatible with render to texture? or am I missing some setting?

if its not compatible - will it ever be? Or is there a better way to bake textures/lights using Vray???

any and all help appreciated!

mkay... this is strange...

When I use lightcache PPT when rendering to texture the texture looks fine, (its using the exponential colormapping like it should - lots of light but no burnt out areas)

But when I change to IRR-map for first bounce it seems to ignore the colormapping and the render-to-texture-texture is much darker and has burnt areas.

The problem with using ppt is that it takes too long... If Im gonna bake every single wall in a big apartment model, just making the baked textures would take a whole day...

any ideas?
