GPU Rendering Makes Tutorial Spheres Disappear

Post by JeffBDVS » Tue Apr 10, 2012 2:07 am

Hi all,

Using the demo of IR 3.2.9 and Cindigo 3.2.9.1.

I have a GTX280 in a Windows 7 SP1 box, and when I render the Cindigo tutorial project with GPU acceleration selected, the 3 spheres in the scene disappear. They render as expected when GPU acceleration is turned off. This happens both in the standalone renderer after .igs export, and in the integrated renderer.

I have the latest 296.10 drivers.

NB: I have a new 2 GB GTX 560 on the way, so if this is a problem due to the older card, then it won't be a problem for me much longer. :D

GPU Raytracing doesn't support primitives atm, but cindigo exports the spheres as such.
You need to break that sphere into a mesh object.

Thanks for the bug report :)

That did the trick; thanks Zom-B!

PS - does this really count as a BR? I didn't even check to see if there was a forum in which to do that. :oops:

Hi Jeff, welcome :)

As far as I know, GPU mode doesn't support Indigo internal sphere (Indigo Technical Reference, page 102). So, the reason could be that Cindigo used it.

edit: oh, late reply :)

If you take the time to let the devs know that something doesn't work, then its a BR, and the best way to get the issue fixed quickly
(people can support your request and tell how much this bug is a pain for their workflow etc.).

If you find issues with the exporter, here is the right place to tell about it :)
