camera render

Post by tuna57 » Thu Oct 20, 2016 5:20 pm

This render was prompted by a several years old render challenge on the SketchUcation forum that somehow got resurrected. Had such a time with it thought I'd post a result over here also. The model was originally posted by J. Kiehlmann.
Rendering this was a HUGE struggle. Something like 95 materials and groups and components nested I don't know how deep. Model was crashing SU and TW at every turn. Using TW V2pro by the way. TW was crashing constantly when I would edit materials. When I would get through materials it would crash when you hit render. I'm sure it's all about the model itself.
Kept at it and tweaked at stuff and posting the last result. Rendered on easy9, 155 passes ( 8 threads ) 3 hours 55 minutes. Beyond the crashing the biggest thing was getting a decent result on the flash unit lens and reflector. Ended up redrawing the lens so it was one solid piece so I could apply my glass material. Originally modeled as 2 separate planes and was getting crazy results.
Applied NK Chrome in deep material editor to the reflector. Seemed to give the best result ? Tried glass-mirror material and wasn't liking test shots so much. Is there a better way to set up the reflector ? Well if you want to pull your hair out give this model a spin ! :doh:

I struggled with the reflector too. Glad you mention it here. My result looks worse then yours

My guess is that the crashing is from deep nested objects, I have seen this happen 3 or 4 times.
The other major crash problem I've seen is some glitchy geometry in the scene. This is usually caused from non-native objects being imported into SketchUP from some other 3D modeling program like AutoCAD. The vertex translation and super-tiny triangles found in some CAD files are not handled well in SU... this is noticed most when trying to export the SU model to a rendering engine, where SU will be like "ok, here's your model, and oh, there's some weird info right here... crash"
One more reason would be high-res HDR lighting. Use lower-res version of HDR.

Image looks great!

jo-ke , TSolt , thanks. it was a pretty challenging model to work with to say the least.

Fletch, Thanks for the thumb. Wasn't really mad about the crashing. Figured it was the model. SU crashed a bunch of times also. Even had to force quit a bunch when the whole thing just locked up and got the spinning beach ball of death. The model looks great and appreciate the gentleman that posted it so we could have a play. But if you get digging around inside of it, it has issues ! One example, I wanted to export the material used on the camera bodies to make a bump map. Never could get SU to export the image. Always came back with an error message. It was most definitely a challenge.

Hmmm... it could have been a very odd image type... not your typical .jpg or .png.

The model is also 6x larger than physical size.

Hope you don't mind me piggybacking on your post! ;) Here is my try with it. It was a pretty fun model to work with but I spent several hours cleaning it up, converting the duplicate groups to components, etc.. However, I can say that after doing that I didn't have a single crash.

Good try at it Chris :^: . 6x bigger ! Never enter my pea brain to check the scale of the darn thing....
