I've been playing around with reflectivity on gem models and running into a strange problem. Certain vertices of the model are displaced from the normal locations. No displacement mapping was used, and displayment mapping was turned off in the renderer. I also turned of the "smooth edges" feature for the object.

Note that it's intersection the floor just to give a better illustration of the issue.

Here is the image without rendering with "smooth lined" selected.

... and here it is rendered. Note the distortion outlined by the floor surface.

You might want to put it in UV mapper and split the verticies....Sharen

yes, sharen is right, use uvmapper.Only way that really helps. Other thing: uncheck the smoothbutton in the obj properties ( works only with the lastes patch) or in the renderoptions

but save your time,also in p5 you will not get a good looking gemstone.several people (including me ) tried without any usefull results.

Turning smoothing off in the renderer and object properties does not help?(P5)

heyas; he said he turned the smoothing off. what happens when you render it without transparency? oh... check for polygons with more than 4 sides. those do flaky things, too. are you using the p4 renderer or the firefly? does it come out differently either way?

Okay, tried rendering with the P4 renderer. Quite a difference.

I'll look at it in UVMapper, but don't understand what that would do to it. Not sure how to "split vertices".

BTW: The gem is from the DAZ3D "DragonHoard" collection; I'm guessing a DAZ modeler built it.

Zenman53186 - not sure if you saw my post over at PoserPros, but I've had luck with the gem models over at 3dlapidary.com - you can download them in a variety of formats, and I haven't seen any smoothing or model problems in P5 with the ones I've used. I did have trouble with the cabachon model causing a c-exception in P5 in the .3ds format (which I reported to CL and they were able to replicate - that was at beta3, it may be fixed now) but haven't had any errors on the others I've tried. If you just need some working gem models for P5, you can try there.

Major thanks, redon; I'll try going there.

Oh, wow, they have some beautiful gems, don't they? Man oh man, candy shop time... I hope they render as nice as they look...

hmmm. is that what it's supposed to look like, that new render? looks like some kinda ray-trace deal then. might want to report it over at the sr2 beta forum.
