I’m guessing specular or maybe weird normal tag from a .obj (or something) dl’d file but I have to see the scenefile

I assume that’s the stone texture in the sampleroom.c4d file, try setting the A015.TIF file and it’s A015BM variant’s Sampling setting to SAT from MIP and set the Blur Scale to 100% (but leave Blur Offset at 0%). Do that for Color, Diffuse and Bump. That seems to help.

the constraint is using Cube.2’s axis to move it and it does stay in relation to the other cubes but that axis is up in the center of cube2. If you use the Axis tool to move cube2’s axis to Cube1’s top like this 13546_constratintrotation1.c4d.zip it will stay where you want. Note the Constraint doesn’t need anymore than just Cube1 to attach to.

not understanding, the ‘sign’ does stay upright the entire time while the ‘posts’ rotate. What is supposed to happen?

Which renderer are you using at this point?
And it looks like the flames on the spheres on the wall cold use an alpha so it’s not a black ball with flame. It’s coming along nicely though.

I never thought to suggest it since you said you tried all the gradient types but why not 2D-V? That should work and will move with the object (without xpresso help) and scale with the size

Yeah I had an early 2008 Mac Pro (and had Macs for 21 years – Amiga before that) and while I was looking at upgrading for a long time it didn’t look right to do the Mac Pro 6,1 ( trash can) I waited for a time while considering a hackintosh (a buddy at work built one) but there is enough trouble with those I decided to build a PC, the Intel’s are kind of pricey and the Ryzens came out… given the pricing of the modular I’m glad I jumped since I can’t write off the price as part of a business. Short story long I guess…

look for tutorials on Motion tracking and Object tracking. Try searching for “motion tracking c4d R19” (also R18 and R20)

I’m late to this thread but some notes on render speed.
Trying to match the shot you posted as Jim did, and as noted without some of the correct imagery, I’m seeing per frame render times of:
– Physical renderer, Adaptive Sampling Quality Medium – 7:30
– Physical renderer, Adaptive Sampling Quality Medium AO off – 6:45
– Physical renderer, Adaptive Sampling Quality Low (AO on) – 1:52

– Standard renderer AO on 35 seconds
– Standard renderer AO off 31 seconds

Can you drop to low quality sampling? I’m just rendering a single frame from a perspective that neither of the cameras in the scene file go to (but that does sort of match the fire in the cage shot you posted) and I don’t see any obvious difference between the Med 7:30 image and the Low 1:52 image.
And can you use the Standard renderer? Physical is the best choice not always. It depends on the features you are using. The differences I see in that limited render example are the bump on the stone wall is a little more crisp in the Standard render and the reflection (specular really) on the iron cage is slightly enhanced in the standard renderer.
And finally AO. From that perspective AO is making a big visual difference with the pillars and the steps but you have it on scene-wide and it doesn’t do anything visible to the metal-cage thing but it’s being calculated everywhere, setting AO into the materials via the Diffusion channel could save some time (a bit but not as much as the renderer choices/settings).
