Bake 3D problems

Hi

I am trying to get bake 3D to work so I can use it for a real time project I want to do.

My problem is that the results I get with a normal render and the baked material render are substantially different. See below:-

Render

Baked scene render

I know that the white lines are to do with the padding, and that the only way around that is in Photoshop, but why is the scene rendering darker and why is the light coming through the window burning out on the floor and ceiling when it looks fine on the render?

I am using the standard vray low settings, Color mapping HSV esp with a vray light set to skylight and one set to mult-5.

Any help with this would be greatly appreciated as it is driving me nuts!!

Thanks in advance

Neil

baking as i recall now doesn’t use colormapping when it bakes the textures. something that i sure do hope they address soon. :cry:

Ah, that explains it then. Thanks for the answer.

Guess I am going to have to find another solution :cry:

So close, but yet so far!!

Surely that’s not why the floor and ceiling are burning out so much though?

Cheers anyway.

See at your corners too.
Bake3D it’s not so usefull i hope it’s improved in Vray 1.5

Me too…

I’m having to use Final render :shock:

So do I :roll:

Can anyone testing 1.5 drop a hint as to whether bake 3D works better or has been updated?? and put us out of our misery please…

Cheers

im scared to ask this here, but how do you use fr to bake vrays lighting maps?

You don’t you have to use FR for everything…

The last release of fr suppors the max native “render to texture”

I hope Vray 1.5 supports it too(also true render passes,field rendering,a good sss shader…)

Yea, but final render “ignores” the GI of the rendered scene when it bakes the texture.

Bake3D and its developers are so stupid, I can save the rendered unwrapped texture image before its display from the render progress screen vanishes and that gets rid of the lighter lines at the geometry seams… so what seems to be happening is the program is saving the render before it is complete.

A few bake3d things.

a: You need to render the scene at least once.. or else you end up with some goofy coloration issues..

b: use meter or feet based units.. ie: 1 = 1foot, or 1 = 1meter.. (unofficial) speeds up rendertimes, and (definite) less blotches in the baked maps..

c: anti aliasing off, or set to fixed rate seems to be smoother in my experiences.. hell if i know why..

d: if you’re getting the outline problems, try shutting off the AA filter, or switch it back to area..

Theres more, but thats all i can think of offhand.

FR and render to texture… it ‘can’ work.. its not pretty.. and its pretty painful in my opinion.. (Probably just due to my lack of fr skills) HyperGI was the only type i could get to work, and it was horrid to try and get rid of the splotching
