Batch process cube maps to diffusely convolved cube map

vvvv beta question
1

diffusely convolved cube map = just a blurry version for lighting.

Does anyone know a tool for doing this in easy batches? Or even better a shader?

I’m just trying to find a tool to do it offline, but saw this if any shader gurus want a crack at it http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter10.html

here is a rough blur filter for cubemap textures - try applying it multiple times to get smoother result

You rock unc :)
That’s Perfect! Thanks! That looks fine after a couple of passes. Don’t need it in real time at all and this will be SO much nicer to use then command line scripts and hours of cpu grinding with some external tool. Cheers.
