Baking problems

[leoviale]

Hi, lately i'm having some problems when i bake my whole scene. I used vray for the scene, then i baked the objects. I used then the standard and apply the the baked textures. The problem appears then, when i'm applying the textures to most of the objects, the programs runs out of memory, and keep doing so, untill i make the rendering and the objects appears without texture. I don't know if there is some solution to this, or i just have to resize the maps to half size or something like that. Thanks.

Why are you baking textures in a rendering, you'd only do that in an animation. Also I'm not aware of any "baking" functions in Vray unless you're talking about saving out LC or IR maps.

Are you rendering across a network? Sounds more likely its a networking problem than a memory one. Are you rendering out textures to use in a diffuse channel to cheat on the lighting? Or as Devin asked, are you baking a lighting solution? Either way, you'd need some very large textures/light file to screw you on memory, unless you dont have much memory that is.

Could you post a screenshot or a render?

Tom.

Well, it's an animation, i bake the whole scene because using vray it took like 40 min or more in every frame. I bake a VrayCompleteMap, like Irradiance maps, lightning, GI all that stuff. Here is a test frame, the floor is not present here.

 

 

There are lots of objects, thats only a piece of the whole model, i had to use like 30 different textures to complete that. Some maps have size like 2000 x 2000 or more. When I put other objects, i get the memory error from the maps im using. I had to resize the baked textures to half size, but i cannot keep resizing them because i loose allot of details. I don't know what to do to fix this problem. Thx 4 the replys.

tried using bitmap proxies?

[leoviale]

No, but the problem is when i hit render, because the render itself has to load all those textures, i'm talking about 180 bitmaps that i use to make the whole baking, most of them r 2000 x 2000 px. U think using bitmap proxies can resolve this?

Hi,

I use baking for my realtime 3d app...

From my experience try using the pluging

 

RTTGroup....

(google it!)

 

It may help you reduce bitmap size without loosing the details.....

 

try it....
