View Full Version : Buffer export problem/bug

11-09-2005, 01:02 PM
Hello everyone,
I've got problem during exporting LW render buffers for further image post-processing. All buffers work fine, except for Refraction Buffer, which incorporates some of reflectance caused by white cards I used in scene (I never use specularity). I think the part of these reflections rendered in refraction buffer is the one that is reflected by inner surfaces (i.e. inner surfaces in hollow sphere). This effect occurs regardless the plugin I use to extract buffers (ASA buffer saver, PSD export, etc.).
Any ideas how to eliminate reflection from refraction buffer?
Thanks in advance

I would think that if you wanted the rgb of the refraction that you'd want the reflection also, but if only want the value of the refraction, can you use the alpha instead? You may have to render this in a separate pass to get what you want.
