sybren Posted October 3, 2008 Share Posted October 3, 2008 Here's something i couldn't find in the posts. The picture proberbly failed to load so let's just explain that I've rendered a model for a good 8 hours but the effect is far from desirable. The reflection on a vase isnt smooth but fractured with every plane of the model. The model isn't highpoly, that I know, but isn't there a way to let maxwell figure things out? The model comes from sketchup and in SU the angles can be made smooth. Maxwell beats SU in realism exept for this little part. Link to comment Share on other sites More sharing options...
Devin Johnston Posted October 3, 2008 Share Posted October 3, 2008 Maxwell is working properly, your vase needs more faces to remove the fractured effect you’re seeing. Link to comment Share on other sites More sharing options...
sybren Posted October 3, 2008 Author Share Posted October 3, 2008 wouldn't a rounded object like this need an extremely large number of polygons? and one more Q, is there an easy way to increase the number of polygons in sketchup. If you know sh*t like that off course. thank you for the quick response. Link to comment Share on other sites More sharing options...
Devin Johnston Posted October 3, 2008 Share Posted October 3, 2008 Well there are things you could do to a mesh like that to smooth it, however I don't believe sketchup has any of these tools so your only choice is to try to increase the number of faces.

sybren Posted October 3, 2008 Author Share Posted October 3, 2008 i think I've found a smooth tool in maxwell.... just a render preview of a selection though so it might turn out for the worst. This forum is getting better and better Link to comment Share on other sites More sharing options...
Peter M. Gruhn Posted October 5, 2008 Share Posted October 5, 2008 I disagree with the increase faces approach. Yes, you could do that. It would work. I don't think you need to. I whipped up a vase in Max and rendereded in Maxwell (materials: max standard lt. gray for all except... maxwell wizard metal silver and maxwell emitter 100w halogen). Attached find images of 9 and 30 sided vase. They are not equal, but neither show the extent of the problem of yours. IMO, your vase needs smoothing turned on. I think that was a problem I had when I first worked in Maxwell's UI. I haven't done that in like a year, I'll go have a looksee can I find it... OK, it MIGHT be per attached "params" image.

Devin Johnston Posted October 5, 2008 Share Posted October 5, 2008 I disagree with the increase faces approach. Yes, you could do that. It would work. I don't think you need to. I agree smoothing is the first thing I would try, but like I said I don't know if Sketchup or Maxwell studio has this function so the only other option would be to increase the faces.

sybren Posted October 5, 2008 Author Share Posted October 5, 2008 thank m. gruhn. The smoothing has no effect at all. I tried various angles, recalcutating and rendering a preview each time but no result. just a shitty fractured reflection. Link to comment Share on other sites More sharing options...
sybren Posted October 5, 2008 Author Share Posted October 5, 2008 [ATTACH]29365[/ATTACH] [ATTACH]29366[/ATTACH] what can anybody make of this. I imported the mesh from sketchup and rendered it in maxwell studio. Being new to rendering in total the flow of the wow factor is uplifting but if this isnt fixed I dont know how long it will last.

Devin Johnston Posted October 6, 2008 Share Posted October 6, 2008 You have the same problem with the glass that you did with the vase, not enough faces. I suppose it could possibly be an issue with the settings you’re using when you export the mesh from Sketchup, see if there is any way to smooth the mesh when exporting. Since I've only briefly used it I'm not familiar with all the options. Link to comment Share on other sites More sharing options...
Peter M. Gruhn Posted October 6, 2008 Share Posted October 6, 2008 Wine glass almost looks like it has ribs running from outside to inside in the glass. This would break smoothing. Seems to me that SU shouldn't do that though. My other wonder is if this is a vertex welding issue. Again, SU shouldn't do that... Maxwell shouldn't have tools to clean up either of those problems as they would be modelling issues. Afraid I don't have a pro version of SU to poke at. Tomorrow when I get on campus I'll try to have a look. Link to comment Share on other sites More sharing options...
Kurt Posted October 6, 2008 Share Posted October 6, 2008 IMHO there are enough faces. Remember: choosing "smooth" and selecting a smoothinng angle is not enough. You have to hit "Recalc" aswell. If this does not work, just send me the scene and I'll take a look at it. Link to comment Share on other sites More sharing options...
sybren Posted October 6, 2008 Author Share Posted October 6, 2008 good point. I checked the model in SU with a translucent material. this is what it showed [ATTACH]29378[/ATTACH] the ´ribs´ show up in SU as well!!!. also a variation in transparency is noticeable. I think I saw it before when using the follow me tool. annoying since this is the only way to make such objects in SU Link to comment Share on other sites More sharing options...
sybren Posted October 6, 2008 Author Share Posted October 6, 2008 If this does not work, just send me the scene and I'll take a look at it. I used the recalc. that probarbly isnt the issue. How can I send you the scene?(stupid) Link to comment Share on other sites More sharing options...
Kurt Posted October 6, 2008 Share Posted October 6, 2008 ok, this can not be solved in Maxwell Studio so I guess sending me the scene is pretty useless in this case... Link to comment Share on other sites More sharing options...
Kurt Posted October 6, 2008 Share Posted October 6, 2008 (edited) just curious: sybren, does this file work: wglass.skp Edited October 6, 2008 by Kurt Link to comment Share on other sites More sharing options...
sybren Posted October 7, 2008 Author Share Posted October 7, 2008 actually no, the file loads in sketchup and the ribs do not show up. other problems do show up when I tried to render(studio). various exporting options later (3ds. obj. dfx. fxb.) it does smooth sometimes but with irregularities, as if the angle is to big at very low angle. I need to get past this stuff. what other 3d program would you recommend since sketchup clearly is the problem. I got some savings, and if the programs good I could invest, creatively.

sybren Posted October 7, 2008 Author Share Posted October 7, 2008 [ATTACH]29386[/ATTACH] Even better. Maxwells setup for materials shows the same problems. look at the reflection of the light via the clear coat. it actually follows the path of the poly´s. Smoothing again doesn´t work. check any of the renders in maxwells material database and there are no crappy reflections there. why? Link to comment Share on other sites More sharing options...
Devin Johnston Posted October 7, 2008 Share Posted October 7, 2008 I guess it could be a bug in the engine it's self, have you tried asking NL? Link to comment Share on other sites More sharing options...

Kurt Posted October 8, 2008 Share Posted October 8, 2008 looks more like a sketchup or plugin bug... Link to comment Share on other sites More sharing options...
sybren Posted October 9, 2008 Author Share Posted October 9, 2008 jup most likely. I don´t know man, the program itself is pretty astonishing but in other ways it´s like walking up the eiffeltower and taking the lift down. There is just no flexebility. any thoughts on a more organic, more flexible, more bugfree kind of software? Link to comment Share on other sites More sharing options...
