Rendering Radiosity

Support Basics & Interface
1

I notice that even when i can see the effects of radiosity in the 3D window, those effects are NOTHING like they are when the render… None of the shading is in the render like it is in the 3D window. Why is this and how can I fix it?

thanks

that is the problem of vertex based radiosity solutions.
it cannot compet with ambient occluson or other systems.

you just see an opengl preview in rendering things will always be different.

with vertex paint you could increase or decrease shadow and highlight information.

post a picture of you problem than i could tell you more.

Yeah sorry. My explanation was kinda messed up. http://xetnad1.netfirms.com/problem.html <–That should explain things a bit better… Thanks

Did you press “Add New Meshes” or “Replace New Meshes”? Then did you press “Free Radio Data?” If you did neither of the first two, do those first (I would suggest using Add New Meshes). Then make sure to free the radio data. Now move the solved radio mesh to a new layer, and render that layer. All that’s getting rendered is your original mesh which, since there are no lights and no vertex light, is black except the emitting mesh.

I would try to post you a fixed blend file, but your server received it as an ascii file instead of binary, and parsed it into a webpage. If you can upload it in binary mode (or e-mail it to me) I’ll be glad to check it for you.

I resent it as binary.

Alrite I tried ray_theways suggestions and its still a little messed up… I updated the link so you can see what the new image looks like.

It looks like you have both the original meshes and the radiosified meshes in the render for the last picture…

If 2 faces line up exactly (which would happen here) the renderer doesn’t know which one to draw on top, and you get that weird streaking effect between the 2 faces.

yep

it looksl ike you have the old and the new mesh in one layer.

move one to a different layer press M and klick a layer number.

:wink: Yep, I got that at one time. Hmm, netfirms still screwed up your blend file. Next time, maybe try zipping it (if they allow zips) or renaming it *.blend.dat, or something.

Its alrite, i got it fixed :slight_smile: Thanks guys.
