Need help understanding Render Warning

jimmulvaney

Hi not sure where else to turn, or what to do so any insight on the following would be appreciated. Progress window gets to 60% and then stops entirely. MAinly using a combination of DG Essential Shaders and Metalized Glass shaders. TIA.

I don't see any problems...those warnings are just informational stating that there are things with displacement 'on' but aren't actually doing anything with it (the 0% thing).  Nothing that is fatal to the render.  My guess is that at the 60% point the render is hitting something that will take a long time to work through...so don't call it quits for at least an hour.

Is it just about to reach a figure with SSS shaders and HD morphs applied? The calculations for preparing an object with sub-surface scattering and HD geometry data can be very slow.

jimmulvaney

Actually, 60% is the Amphora from Magic Containers. It has the Metalized Glass Shader applied to it though. I still work in 3Dlight (until I upgrade my pc) and Luminance for Uber Enviro 2 lights.

Thanks, I will have to do a render when I get some time to walk away next.

Well, time did not seem to be a factor. I thank you for all the advice but in the end I used a different glass shader and there was no problem. To recap: it took less than 30 mins to reach 60% but then I left it for more than 4 hours and it never went past 60%. I used a different glass shader and the entire render took 40 mins (5400px x 3600px, going to be printing it @ 150dpi), plus it looks phenomenal! Also I should mention I got my shaders mixed up. The problem shaders were the glass shaders from DG Shader Essentials and the shaders that worked for me were the Metalized Glass Shaders.

Gonna PM DestinysGarden and see if they have any insight.

That set is essentially a bunch of presets for omUbersurface.  Glass in that has always been very slow...at least without tweaking.  Pretty much need to do some of the same tweaks for glass as for hair and pay careful attention to bounce depth.  And since it was omUbersurface...4 hrs may not have been enough time.  On some, in 'normal' (not progressive render) I've seen 10 or more hour 'calculation' times for it.

DestinysGarden

MJC has the right of it. Glass in that has always been slow.

 I didn't do anything special in those presets except plug in image maps and create surface settings. I know Daz Studio has been having random issues on and off with the UberSurface shader. I've gotten so used ot ignoring that error message that I forgot it existed. I think the Metalized Glass Shaders were a custom job set up in shader mixer, so I'm not surprised that they functioned differently. In the interest of trouble shooting, do you have any other shader presets that also use the OmUberSurface, or can you apply the base shader to an object and see if you get the same error?

jimmulvaney

Cool, thanks for the feedback everyone. Not sure what omUberSurface is. I tend to use UberEnvironement2 for my AO renders if that explains anything. Well, I guess I will just avoid using those Art Glass shaders all together, the rest of the pack still works great! Plus I have a massive selection of shaders I doubt it will be a problem. If the error is a moot point then I won't concern myself either. Also, I am still running DS Pro 4.8 because of 4.9's lack of flagging new content in the content library pane.

Did you try setting progressive render on in render Settings? It's more prone to noise, but it can be a lot faster than the bucket render on complex shaders (uberSurface is a surface shader from the same author as uberEnvironment and others).
