What’s your active renderer? Also, if you’re using Rhino 6 for Windows, what does your SystemInfo say about the graphics driver? Either of those things could impact Rhino lights. If you are using light objects from another render plugin they may not support the Rhino Rendered mode.
For this situation I am using rendered view, haven’t changed anything in options. I looked at settings and the Display pipeline is OpenGL. Realtime display engine has two options Cycles and None. I have None selected.
I am not using Cycles (raytraced) for the preview (if i switch to Cycles the shadows work just fine).
The reason is that rhino calculates shadows in OpenGL only from spotlights (and a pointlight is kind of a set of spotlights, so I know linear lights could be simulated with multiple pointlights, and the same with rectangular, but at a cost since many more shadows would have to be calculated for every single frame (as I don’t think Rhino stores the shadow information)
So a spotlight makes a “hard” shadow, but it appears soft if the object is small compared to the light since the shadowmap isn’t super highres and the interpolation of that information will be a gradient. (if that makes sense)
But with modern RTX cards and realtime raytracing we will hopefully see some nice upgrades in the future…
Hi, well the 300dpi should not affect the size since renderings only care about the pixels and the dpi only tells the real world what default size to print it at.
But as you can see my example took 6 seconds for 50 iterations, (note 50 isn’t many iterations) so if you still see grainy images at that few iterations I presume you have either a large scene or shiny materials. Could you post an example image?
If you are using Raytraced with ViewCaptureToFile/Clipboard to render and you find things too grainy you should install the denoiseraytraced package using the _TestPackageManager command. Once setup properly (use DenoiseRaytracedCheck and follow instructions) you should see quite some time savings and much smoother results.
If you’re using Rhino Render with the Render command then… I don’t know (:
Ah… yeah… the Rhino Render… don’t get me started
Nathan made an excellent Cycles render plugin too, that didn’t make it to Rhino 6 as default, but you can install it through the hidden and also great _TestPackageManager:
Great for larger than screen renderings. But @nathanletwory does this support Denoiser too? If not, could you update it so it does? Together with supporting Raytraced view that would be awesome!
If I feel I need to postpro I generally do that in the compositor of Blender, or just with GIMP. But if you’re happy with the postpro effects from the Render Window you definitely should use them (:
Oh, it’s more, it has realtime feedback on higher than screen resolution and you can’t accidentally move the view and you can safely save it after it is done without using hidden viewcaturetofile commands.
And you can set the resolution and always get the same size in a known environment.
(So as you see these points are all about userfriendlyness and has nothing to do with technology from my point of view )
((But I rarely use it since I’m a nerd and viewcapture hacking has become normal for me, but I hesitate to recommend viewcapture to customers))
