A screenshot of your save and output tabs would help. Otherwise... Full HDD? HDD in sleep mode?, External HDD disconnected?

Nice! Thank you - good read there. Gonna dig into this a bit more - I want to make this work for Cinema and Corona or Redshift. I knew it wasn't new, but was lacking the correct verbage to track it down. Thanks Mike A - very useful!!

In Redshift look up the OSL (Open Shading Language) shader node. You can download text based OSL shader files to plug into that node here: https://github.com/redshift3d/RedshiftOSLShaders One of them is the jiWindowBox shader. That's what you want. I know there were some issues with it last time I used it - quite some time ago, but it may have been tweaked / fixed since then. There was a discussion about it earlier last year - and I posted an example - here:

Also, it appears he's giving away a free plugin this week as well.

Meshes too? I remember the trick of using fields from a scatter parented to the camera. It bogs down easily from what I remember.

Like this? C4D camera culling.mp4

Well you either mean tokens or takes but it could be either !! Or do you mean to ask OP if he was stoned at the time ? 😉 I have also never come across this error, but am equally powerless to speculate what happened without knowing the scene / project /output settings and the state of the hardware in question.

The asterisk following the filename in Picture Viewer already marks files, which have not been saved. I don't think I ever encountered such an issue. Not sure anyone will be able to help here. Without actual paths and project files or at least render settings, it will be impossible to say what has happened. Have Tokens been involved? Is it possible the drive was temporarily full? Any chance saving had been disabled in Render Settings? Edit: Typo

Yeah, Corona Render also has a Scatter tool and Camera Clipping too. Helps reduce the load with objects off-camera. The processing is surprisingly fast as well. I'm sure C4D can do it also, but how fast.? Are you doing animation? I'm going to assume you've tried closing sections of grass (mesh of a section of grass) and clone them around and randomize a few settings. This technique works best with mostly flat areas however. I did this image in Corona before it had the Scatter tool. The grass was cloning grass meshes and mixing in some other plants.

Octane really has a sexy scatter tool. I'm not sure the renderer you're using though. I do wish C4D had camera culling like Houdini.

Yes - this is correct. The RS sky model is based on an analytic model of daylight. You can select the older 'Preetham' model, or the newer 'Hosek-Wilkie' model. The latter is recommended. However... Rs also supports the C4D Physical Sky shader as well. So if you want more artistic control you can use that. One note: The C4D physical sky is baked to a texture, so you will need to increase the texture resolution for detailed results - typically 8k+. I'm not in front of Rs right now, but there is a setting in Rs render settings to set the resolution as a default, or you can set it in the material texture node. ** Having written this I'm not sure if the Phys Sky is supported in the new nodes shader system, or just in the older Xpresso shader graph. I'm using the latter in R21.

If the sun is part of a sky system its own color /intensity / atmosphere controls are greyed out, and these things are controlled from within the sky object's sun tab instead I think. CBR
