Sample scenes "Cannot render photon maps"

Post by olahaldor »

I simply load a scene and hit the KrayFrame button. And in the Render log I'm presented with a line
!!! Cannot render photon maps

What's this? I switched to Photon Maps, same message, then back to Light map, and I still get this message.


I'm at home now, so the specs are
Win 7 Home Premium x64
Core 2 Quad, 8GB RAM
Mac Pro 8-core 2.26GHz Mac OS 10.8.2
LightWave 3D 11, LWCAD 4.2, Kray 2.51

It means kray doesn't like something in the scene. Probably it's some material (or strange light?) that is throwing off calculation of photon map. This is what you can try:
add Kray Override shader and select "Pure diffuse". If it renders ok then it's some surface parameter. You can then remove couple of objects and see if you can find the one causing problems.

Once you strip down the scene to a small enough size you an post it here so we can check if there are some bugs there and find the solution.

I've been away for some hours now and I loaded a scene again. It's rendering fine now. What I've done is shut down LightWave - been gone for a few hours, open LW and a scene and hit KrayFrame again. Really, really odd.

Good looking scenes though :D

Hehe maybe this is just what it was trying to say to you... Get some time off - you've been working too had. ;)

Hehe, good point. I often take work back with me home. Maybe it's time to buy myself a wife and download a house. 8)
