Render bake help
-
Hi all,some of yo maybe remember me from past and I hope some of the oldies are still arround
.
I stoped udeing sketchup long time ago but now i need it again and since i been away to long from it I need help.is there a rendering software that can allow me to render/bake texture on model and export texture with the render/bake effect on it? -
Hi Ivica!
LightUp, perhaps? I haven't tried it myself but I understand that it uses some kind of baking - don't know about the exporting, though.
This is something that interests me too. For instance, it could be a way to export lighting effects into 3D PDF.

Yeah, I think LightUp does just what you want. Then you would probably export it as .obj to keep the textures I guess?
-
I think it uses fbx with the baked textures but yes, it can do it.
@Anssi; SimLab composer can export rendered models with baked textures to PDF.
And welcome back, Ivica!

What is a baked texture?

When shadows and such are not really cast on the faces but the texture is kind of modified with these shadows. It has the advantage to run faster as you do not need to dynamically update the shadow function as it is "faked" (baked) into the texture already.
Also, if there are other shaders (like bump maps, you do not need to load them either as when the shadows were created, it was already used so it is not necessary any more.Of course, not everything can be baked. Baked reflections may look okay from one viewpoint while totally off from another.

Look who is back.....

Thanks for the explanation Gaieus. I am not sure I fully understand, which
has little to with your explanation and a lot to do with my brain.p

Essentially it is taking a render of a model and actually applying the render imagery onto the geometry. So when you see the nice photoreal renders that do intricate shadow work, and light bouncing off colorful objects onto the walls, and add "bump" detail to materials, etc - all that gets rendered, and then actually applied onto the model. So then when you navigate in SketchUp, it looks like a photoreal model that you navigating around. Check out LightUp. Its exactly the stuff that he is doing there. Its quite impressive.
Games use this technology and have for a long time. It is CPU intensive to render really nice shadows, bump maps, ambient occlusion, final gathering, etc. So instead, they render it once, then apply the rendered materials onto the geometry.

Thanks chris. I think I get it.
