stevenyhof Posted December 2, 2020 Share Posted December 2, 2020 The first ray trace I did took a few minutes. I stopped it because I got impatient. But it must of just finished because I have it. But I could not get another one since. Last night I had it run over night and it is still not done. I did a preview and that worked. I did a larger preview and that just worked. I even changed the time to just 1 minute, but that also never stops. Thoughts? Link to comment Share on other sites More sharing options...
stevenyhof Posted December 2, 2020 Author Share Posted December 2, 2020 Well, now I am adding passes and that is taking a few minutes. I'm at 7 now which looks bad, but the time is not so bad. So I think I'm ok. Link to comment Share on other sites More sharing options...

I think I gave you my email in past...send me your file and I can run this for you on my main machine if you can wait a day or two Link to comment Share on other sites More sharing options...

I keep adding passes, at 15 now and it still not looking great. I figured I have a lot going on. Question: How many passes is minimal for a nice pic? I will try that first - it is working faster now.

That's a real unknown as it dep[ends on many things such as lighting, number of reflective materials, number of transparent materials (especially when they are on top of each other). Also the size of your pic, with Raytrace if you double the size of your pic it will take 4 times longer per pass. Some traces could take hours/100's of passes. My personal tolerance is about 30 passes which might take 10 or 30 minutes on my system. Link to comment Share on other sites More sharing options...

Many more things too such as number of faces in the model, Ray Trace settings (photon mapping, caustics, focal blur, etc. etc.). Ray tracing is an art form and for all intents and purposes is unlike anything else Chief related. Link to comment Share on other sites More sharing options...

stevenyhof Posted December 2, 2020 Author Share Posted December 2, 2020 I would like to ask, and I think I know the answer to this while I am waiting on the trace, is that, the picture shows up after like 2 or 3 minutes, so I am assuming that it is continuing to trace? I just took a picture of the screen and now while I wait, it does seem to slowly get clearer - but not really sure. Will it tell me when it is done? So far I have moved on and get a message that it is still working. And while I type this and look at the picture, I cannot say it is looking any clearer. Thoughts?

There is no message when it is done nor does the program have any way to determine this. You decide when enough is enough, each pass refines the scene, at first this refinement will be fairly dramatic but as more passes are completed the refinement will be more subtle. At the bottom of the screen there is an indicator that tells you the number of completed passes and the total time. Link to comment Share on other sites More sharing options...

You do know that you can control the image size and the duration of the ray trace in the Ray Trace Options DBX? These settings must be made before the ray trace is started, and once started can't be altered other than to stop the ray trace. You can set the ray trace to run from 1 minute to 24 hours or you can set it to run from 1 to 999999 passes. If you really need a million passes you can set the ray trace time to no limit and it will run until you stop it or your machine melts into a tiny puddle on the floor.

I decided a while back that the flat head screw is the worlds longest running (and perhaps most successful) practical joke. Whenever we start taking apart a structure that was built 50 years ago...all tied together with 100's of flat head screws, I can't help but think it was some diabolical genius that pulled that one on us and I imagine he's looking down from Heaven laughing his tail off. 1 Link to comment Share on other sites More sharing options...

Well I must be doing something right as that plan is titled "Flat Head Screw". I just wanted to add a spot of realism to some hardware I was modeling. Apparently Mr Phillips felt the same way you do.

A special bit that gouges the screw head into an inverted cone? @stevenyhof Before you raytrace that scene, you should see if you can adjust the facet angle of the drywall arch. Try 2 degrees, it'll smooth it out nicely. It looks like you used a p-solid, right? Link to comment Share on other sites More sharing options...
