Member DMG Posted October 1, 2022 Member Report Share Posted October 1, 2022 (edited) I was going between 3DC and Blender a bit trying to hit the sweet spot I wanted for something, and I noticed differences between the two renders, especially caused by varying roughness values. I decided to get a bit scientific about it, so here's the results of my tinkering. I used the studio.exr panorama from Blender in both programs for a fair comparison. The 3DCoat environment settings were left at default, but the light was deactivated. The HDRI was normalised when I imported it. The HDRI strength was left at default value in Blender too. A simple sphere, identical colour value in all renders. I'm making no judgement as to which renderer is 'better'. This is just purely for comparison, to see how roughness values appear in each in order to make texturing a bit more predictable. I did notice that in the HDRI there is a tiny but bright spotlight high up adjacent to the other light, but for some reason this isn't picked up in the 3DCoat renders. Perhaps it's just a tiny pinprick and too small to be picked up. I don't know. There also appears to be a light down low, right of centre, but only on the renders for 25% to 40% roughness in the 3DCoat renders. I don't know where that's coming from. It isn't apparent in any of the others. The most noticeable differences is that the reflections in the 3DCoat Paint Room preview are a touch more intense than both of Blender's renders, but the same reflections are a bit feinter in 3DCoat's Renderer. Also, at around 35-40% roughness, the 3DCoat Renderer has greater blur on the main reflections near the centre, which has almost become a single bright patch, whereas all the others still have two distinct light sources. Like I said, this isn't about picking a 'winner' or 'favourite'. It's just to help me predict how my textured objects will appear and render in Blender to save time to-ing and fro-ing making adjustments. Just thought I'd share.
