Parsing, Components, and Workflow

Re: Parsing, Components, and Workflow

thanks thom for putting this at sketchucation. now this parsing has shed some ligts to me how vray reads the sketchup geometry. As for me, its really critical that i would see my applied materials in sketchup as they are. i really find the ease of SU in putting the materials in sketchup. now if the problem is reading components. would it be correct to say that let's just do group in modelling and dont use components (if vray parse better with groups). anyway i rarely use components in my workflow. since i don't like identical twins in my scene. but i hate to see that what i applied in sketchup will suddenly be change by vray. perhaps an explanation how vray parse the geometry should be explain much clearer to warn the users during the modelling time in SU. anyhow i will keep on coming on this thread.

The question is: do you often apply materials to groups/components?
Or do you always apply the materials to the geometry itself?
Would it be ok if V-Ray ignored the group/component materials and only read the material of what's applied to the actual geometry in order to cut down parsing time?

Re: Parsing, Components, and Workflow

nomeradona,

Groups themselves will likely not be affected significantly by the discussions of this thread, and likely not show any much speed increase. The reason being that they are considered almost completely unique. It isn't unless you have direct copies of a group that there will be any real increase.

I agree that I would rather not have a rendered result be different than what appears within the SU model. Thats why these options for parsing would be off by default, so the rendered result would match the viewport. Only a user who understands how these changes affect working in SU should use them and has to enable this option thmeselves.

i apply it to the geometry itself not group.

I can make a new paintbucket tool which paints the geometry inside groups/components to ease the workflow. Option to paint faces, edges or both.

wow another good toy thom. thanks in advance.

Re: Parsing, Components, and Workflow

I realize this is a few month old, but I'm curious about something. How much is parsing affected by projected textures or textures repositioned with the SU texture tools?

I ask because I had a model that was parsing at 13 minutes.
I ran Matthieu's remove C-G materials script and it dropped parsing to 12 minutes. (still unacceptably long)
I figured it must then be the groups and components, so out of curiosity, I used the bomb all script to explode the entire model. (which took 30 minutes! arghh)
Hit render again and it parsed for 11 minutes on a model with no groups or components at all. How is this possible? What other factors are contributing to the parsing time. Got me wondering if it was perhaps the projected textures that where slowing things down more than anything else. Could this be?

(I'm using the latest release)

Re: Parsing, Components, and Workflow

I've seen this as well, that removing materials and exploding doesn't decrease the time at all. In fact, I experienced an increase when I exploded the lot. This was a ~200.000 face model - imported from Revit. I think that it maybe just takes that long to process that many entities.
