Displacement Insanity

[aggiechase37]

Displacement works in Live Viewer, but not in the Picture Viewer. Can't find any other circumstance where this is the case. Help please!

Hi aggiechase37,
sorry but I have tried your scene and I wasn't able to see any differences between LV and PV, at least with v3 alpha 6.2
anyway it seems that you have some weird scale settings, a couple of instance objects are inside their reference and the film buffer is set to 8bit instead of Floatbuffer:roll:

I'm using the 2.25 latest version. Maybe that is the culprit...?

I actually got it going by changing "geometry control" to "all objects movable." But this absolutely killed render time. Goes from 10 minutes per frame to close to 2 hours...

[aggiechase37]

Downloaded 3.0 alpha. Still had to check "all objects movable" otherwise top screw is flat, and render time still horrendous. But it's down to an hour! There's got to be a better solution.

Also, what does that mean "couple of instance objects are inside their reference?" I did scale up those connectors. The room is good scale, but the connectors are usually about 4 inches and scaled them to be about 6 feet, like they're soldiers in the room waiting to be deployed. Not sure if that would have something to do with it...

1- Disable Sci-Fi-3D-Room Instance and Sci-Fi-3D-Room Instance.1. They are referencing to their parents and causing two more copies of all model at same point.
2- Disable displacements and use models rather than them. It seems making very slow in case.
3- Don use 8-bit buffer, use float(tonemapped)

Most criticals are these. Keep all render settings on default if you don't know background of that how works. Auto mode is best for non-expert users. It decide to which is best for you.

Here is optimised scene without displacement. It's about 2:30 with PT on me.

Thanks Aoktar! I certainly appreciate it. I'm in Central Time U.S.

I'll have to figure out a decent way to make those screws. It took me forever to figure out the displacement trick. Displacer effector seems to be buggy or something on C4D R16.050. Can't get a gradient to stick. It always gets stuck, and then resets a plane to flat. Anyone out there know any nifty modeling tricks to make screw threads? (And don't say anything about the helix spline. I can't get it to terminate at the end correctly)

[aggiechase37]

Ok figured out a pretty decent system for threads. If anyone needs it I'll leave it here.

You may also use a curved spline and a Lathe Nurbs with a Movement and a higher Angle (like 3600° by sample).

That's a pretty good idea too. Thanks friend.
