On the left is 1 Substep and on the right 3. The sims are bigger with more steps but the detail also. Rendered by a tutorial customer in Redshift so I do not have the render times but can find out if needed. Tutorials available see my YouTube Chanel

3Delight is free for up to 6 cores- 12 threads and watermarked if you want to use more. But at the end of the day with Render farms being relatively cheap you are really only looking at look dev on your personal machine. A dual CPU xeon can be had for a very reasonable price ( second hand).

If you do a search on the forum you will see R23 is buggy as hell for many here, you could try an older version of C4D and see if that brings stability.

Of course it could also be a motherboard issue..forget C4D put it on a full stress test program, if it crashes then I would suggest sending the whole kit back for a replacement..IT SHOULD PASS ALL STRESS TESTS...assuming you have not messed with the BIOS overclocking.

Try setting everything to max. PS and Windows

what about windows power saving profile ?

Is it a variable supply ? if so at 550W I doubt if it has enough power and may well be crashing before the wattage ramps up. Try Windows power profiles and see if changing them helps

May also be a power supply issue how many watts do you have ?

Try stepping back the GPU drivers..I have heard that the latest can cause issues..as usual..they give them to us to beta test them live. Sometimes I have had issues with Studio drivers when the Game Ready driver is fine.

Why do these members bother to ask for help ?

Give me a basic scene file and I will have a look. What version of TFD are you using ?

You need to add Fresnel

Give us a nostalgic screen shot please. I think my first C4D was R6

I am rendering out to passes and have done a camera fly using the "use camera path option in the light mapping and irradiance cache as primary. My frames render at around 40 secs a frame. Now the GI is calculated and saved but I want to make some changes (16 bit to 32bit) and I render with GI set to auto load and yet my renders go up from 40 secs to over a minute a frame..the GI is already calculated so it should be faster..what is going on..any ideas ?

OK rendering out to 32bit passes seems to solve it.

If I go back to the picture viewer and manually save the pass it is ok just needs gamma correction...this is on R20..I will test on R21

I have rendered out a scene file with physical sky as GI and all looks fine in the picture viewer, I wanted to comp my shadow pass on it and blur that but when I load the diffusion pass in fusion or irfanview it is all red yet shows OK in the picture viewer. I a saving as 16 bit. Any ideas.

Yes that is part of a set of scenes i plan to do. What i am trying to do is master all the tricks of fast..FAST renders. Billboards, pre rendered sequences, baked textures and lighting, proj mapping etc. Then I want to really make use of Fusion, something I have been gagging to get really into. I have a subconscious critic who is always saying "That is cheating" for example in TFD i spend hours, days trying to get an explosion to run using real world physics fuel burn etc when I could sculpt my explosions, the end image is what counts not how I got there. It is all just smoke and mirrors and I want to leverage the concepts of game playing with photorealistic rendering so that a Hollywood level 10 sec clip can be created and rendered out on a home PC within the lifetime of the artist. However I want to stick with one rule..no stock footage. I am thinking along the lines of a battle of Stalingrad or Berlin style street scene. I would do love to get more into Redshift but I find AR far easier to shade and render TFD with. I may take the approach of rendering scenes with RS and comping over any AR layers. Though for my purposes URender could well do the trick. I am thinking about very dusty/smokey hazy low light street scenes and though GI stability is crucial most will not need crazy detail in the renders, post and scene action will cover any minute imperfections. I am using Kitbash models and they should be fun to work with for building collapses however I can see such scene elements taking a long..LONG time to set up.

Just testing advanced render see the youtube video for the full on blurb

Use a fluid sim , x-particles has one I think. I work with turbulence FD

Your welcome

Make a sky with a gradient texture, add an infinite light and give it a sun tag and adjust the time. Add some GI or an ambient light if needed

Seems fine now..as I have said many times before the forum is fine it has all the members need..if it aint broke don't fix it.
