Random white specks in IRAY renders

Ryuu@AMcCF

I'm not sure what I'm doing wrong, but my renders keep having random white pixels scattered over the entire scene.

Also, I'm trying to create a skid mark effect on the ground behind the griffon to show how far he traveled when he crashed slid landed.

The preview looks good, but the render is rather lacking.

      

I hope someone can help with this. Thanks.

Your preview is Texture Shaded and not Iray.

Did you already tried to change progressive settings? Set an higher Max Samples/Max Time and maybe Rendering converged ratio to 99%

A bit of an 'educated guess', but that noise is probably caused by the 'TD3_Atmospehere' object in the scene. AFAIK, that is used for 'atmospheric effects' like light rays etc. It does take a lot of iterations for the noise to clear, and thus alot of time (esp on cpu only...). Try hiding or deleting the 'td3...'

Yep, I recognized that scene as soon as I saw it. I had the same problem. Never did figure out a solution other than hiding the atmosphere.

As far as skid marks on the ground, OP, you could try using a deformer to make depression in the ground, or make a displacement texture, but that would probably increase render time with such a large mesh.
