View Full Version : Camera animation (turntable) with HDRI and GI

04 April 2012, 12:46 PM

I'm trying to do a camera animation, a 360 degree turntable using GI with a HDRI as lighting. I'm trying out the IR+QMC (Camera Animation) but get very varying results.

If I render a long seqeunce of images, let's say all 300 frames - I get very moderate GI results with spots and such. I'm using the irradiance cache.

However, if I change nothing but the sequence and limit my render to around 20,30 frames - renders look very good. Also, I flushed the cache inbetween the tests.

What could be going on here? I change nothing except the numer of frames I launch the render for.

Should I use this GI mode for a turntable? or do I have to use sky sampler?

Best regards

Are you spinning the object or the Camera? For a turn around if it is the camera that is moving, even camera animation mode is a waste, just bake the objects textures and it will render in essentially realtime.

Yes, I'm only spinning the camera. I'm not sure what you mean by baking the texture, could you please elaborate?

It seems that when I use the sky sampler, everything looks good.
