I removed the refraction, kept the diffuse the same and it rendered fine but slightly slower.

now.. this sound quite "unusual"

RT generally works instantly on the lighting/ camera position/ material definitions. The mesh has to be exported again if you make geometry changes to objects in the scene ..... However, I think a CUDA card will be on my xmas list.

have a quick look to the whole scene and lighting is still "magic", considering i spend the most time in setting to properly place the camera, adjust sun/lights etc..
and i just got a cuda card so.. can't wait!
but, if one can't see the proxy group in the viewport or move it in rt preview, how the placement/snapping of this object will be fine-tuned?

ok i will try 40 subdivs. thank you sir.

mmm.. actually quite low (err.. default reflection subdivs in image 2-3-4 but 20 subdivs for the steel in image 1 wich is getting the same issue.. i will try to rise all of them to maybe 24 nex shot..
but.. what about with the fresnel parallel set to black? do you think is that ok? how parallel exacltly acts? i can't find some good tutorial on that..
thank you

i have those strange artifacts on object borders. the borders are rendered black on smoothed surfaces with reflections.
how can i get rid of this problem??
maybe i have to set properly the parallel fresnel colour (i don't know how it actually acts, so i leave it to default black every time) i suspect this because smoothed surfaces without reflections are not affected by this issue..
the only way to reduce the problem is to raise a lot the policount, but it does cost ram, and most important it actually does not 100% solve the problem..

it should be

it would be perfect.
so i can add zillions of trees and see them real time.. nice

nice.
will the new vray support layer animation and/or texture animation?

thank you thomthom very nice videos, but they didn't fully answer my question, the point is: will instancing work WITHIN the rt engine? or they will be available only for the final render? (as shown in the video above)

were i can find some video/demo of the proxy thing (maybe related to vray 4 rhino)?
and how does it behave with rt engine?
as far as i understood, the proxy is an heavy poly mesh linked to a low poly object in the sketchup viewport, is that right?
for example (if i figured well the wole thing) i can place 2d billboard trees in an exterior scene in SU and link to the billboard component a hi poly tree model.. now in the rt preview what will be shown, the billboard version or the hig poly one?
sorry for my bad english, i hope the question is understandable

have you checked the use 'colour texture as transparency' in the diffuse rollout.

he did it for sure, elsewhere transparency would have not worked in the diffuse
I would rather check if the material was properly applied to the backface, cause that can lead some problem. i suggest check if the material is applied on the front face (turn on monocrhome mode and check) and then use "frontface material to backface" from thomthom's UV Toolkit

my 50 cents to help your quest.
recently i discovered that for the textures rock - stucco - smoke - snow - speckle - splat - water you should untick "use 3d mapping" to enable UV tiling control.

great edition as ever! very intersting! congrats!

Thanks Marcello, but i figured out the problem,for some reason v ray would not render with lights, as soon as i deleted my lights, it began to render without any problems. I'm not sure why this happened though..

did you make the light a component? if so that's the problem. there is a bug that crashes vray if you take the vray light group and make it a component.

if you need it to be a component i suggest you group it with some other geometry and then make a component out of this new group. (i find the most reasonable thing to do is group the vray light group with the light/lamp fixture group and then make the light+fixture group a component and it will work nice even if you copy it)

sorry for my bad english

nice! i was here to do the same exact request because i just modeled an hanging cloth and found that having an option of "only connected" for soft selection would be really cool.. i know 3dstudio max has a sort of cloth simulator, but i find 3dsmax is.. how can i say.. a "bit more expensive" than your tool..

oh.. and "merge to point" rules!!! go for it!

if i don't remeber wrong you have to uncheck it from window/preference/extensions before you can load it on demand.
hope it can help

i think (and this is not true for sketchup or vray only, but for most apps) that when you format and resume a pc, or simply move a project from a machine to another, that you should first of all make sure you rebuild the same path for all linked files.
otherwise all the links in your project will be broken.
for example, in your case, is it possible that your project needs you to reinstall the folder/folders containing all the bump, reflect maps, etc.. in order to properly display rendered materials..
so, are you sure when you re-installed your project data you re-create the very same footprint for all of the project folders?

tank you!

There is a separate Sketchup sub-forum within the Otoy Octane forum, where all of the versions of the exporters are available

any working link to this? i tryed to google it, but the octane forums seems to be offline..

it's slower than molasses when rendering

that's true..

uncheck gi or set multiplier to 0 and also uncheck default lights.
