V-ray rendering problem
-
Okay, guys (and girls). I'm finally here, realizing i can't fix the problem i have continuously with my project. So that's why i'll ask the best and more experienced like you.
I have v-ray 1.49.01 for SketchUp 8 pro. The problem i have is terrible, cause sometimes it's rendering and sometimes it's not. I mean... Sometimes the render window does not appear at all. There's just a flick and nothing. And... I don't know the reason. And i'm loading the same file again and when i don't mess up for example with one particular wall i have in the project... Then the render window pops up and the render is fine. But then.. I'm copying two three objects (spotlights) and i'm clicking render again - and there we go again - nothing. I have that problem two weeks. I haven't load textures beside those from the sketch up. And... All of the objects are appearing fine, when in some particular point it just refuses to render or even to show render window. I don't know what to do and what can cause that. Any ideas? Thank you in advance.
P.S. I can upload the file somewhere or to send it to someone. I really need to understood what causes the problem, cause i can't work like that...
Help, please. -
Anyone?
-
when copying objects, do you have two sketchup instances running (each with a loaded V-Ray)? it is known that two running sketchups and vrays cause problems.
-
No. It's only one single SketchUp window opened with v-ray runned in it. Does anyone seen something like that? I reinstalled the program on a different computer, but the same again. So i think it's from the file or from the way i'm working.
-
couldn't the spotlights be the problem?
as they are vray objects, it is possible that they are buggy. can you try with an empty scene, if it exhibits the same behavior?
-
I thought they might be, yeah. I deleted the layer and i tried to to other stuff. Like to copy a different object or something like that, but after 1-2 steps - again - just flick without render. I tried also to render some of the spotlights and they're fine. But when i copy more of them (because of course they can't be for example 10 spotlight in the whole bar)... Then again it's not rendering. Can i send you the file so you can take a look those days. (when you have time) It would be great, great help.
-
sure, upload it here as an attachment, and i'll have a look at it (and maybe someone else will look at it too), and we'll be closer to solution
just to clarify, if i understand it correctly - you open the scene and it render every time. then you copy few spotlights and at first there's just a flick, and on the second try vray renders properly? -
Pff.. Thanks a lot. I really appreciate the help!
As far as concerned to the v-ray render. I'll try to explain better. The file i have is not finished (of course). I have downloaded some objects through sketch up and i used them. Most of the things i have made, but not everything. So i'm using some downloaded spotlights. You can see them on the circle and on the part of the wall. I put emmisive light in them so they can look like the source of the light. I also downloaded some photometric IES lights from luthonia and i used them. The PROBLEM!!!
The problem is that i can not finish it. I mean that when i try to copy those spotlights(only the object), the v-ray is not rendering at all. It starts thinking... Then a flick and nothing more. And you can't just roll back the operation and start rendering again. It's just becoming useless and i have to close the file without saving it and then to open it again. When i do that it's rendering, but if i touch something - the spotlights OR if i put more IES lights OR if i put rectangular light... No matter what i'm doing - it's not rendering.
... You should try couple of different variations so you can perfectly understand what i mean. That's it for now. I'll upload the file, including also the IES light i would like to use(of course - you can switch it with other/ i've already tried that thou) and some jpeg screenshots of what i'm trying to do.
THANK YOU a LOT!!! (bow)
P.S. I couldn't upload it here. That's a link for download the file, the IES lights and some renders with explainations.

i attach first your explanatory pictures, and then my render.

i opened your scene, and so far i've been copying lights around and vray always rendered for me o.O
if after closing and opening sketchup it works, do you think this could be a lack of memory issue? what is your pc's configuration?
EDIT: also, are you sure nothing happens after the flicker? maybe the scene is just being parsed; the task manager doesn't show any cpu usage?
Hello! I have a similar problem. you click on the render button and it remains depressed for a little while and just comes back. The render window does not open at all. I have rendered much more complicated scenes on this pc, so the configuration, i guess should not be a issue. but i am not sure. this came to my mind too. someone please help. i am stranded with a very elaborately modeled scene and i cant render it.
-
Okay. First about my configuration.
CPU - QuadCore , 4050 MHz (41 x 99)
Video Card - NVIDIA GeForce GTX 470 (1280 MB)
RAM Memory - Corsair XMS CMX4GX3M1A1600C9 2x 4 GB DDR3-1066 DDR3 SDRAM -
I'm seeing now your render and as you can see in the first picture of mine that you've posted... You can see that when the IES light is one it's rendering. I'm really curious you to try putting more (4-5), but ALSO rectangular lights (copy them from the other) and ALSO emmisive lights. I can see also in your render that the sofas are gone. Why? Is there any problem there? I don't want to be insolent, but can you please try to put for real emmisive layer(copy them from whatever you want), but also the IES lights AND the rectangular. Everything is there(in the circle), so it won't take much time. I'm really thankful for what you're doing. I didn't even hoped for something like that. (handshake)
-
One more thing.. In the chandelier i put rectangular lights that when i touch, the program crashes OR if not and i enter in the v-ray light options of those rectangular lights and i put higher level of intensity or change just something... The v-ray rendering frame is again the same - flick and then nothing. I'm starting to think it's the v-ray version. But can you also try just to boost them? After all that's a light source. Are you using 1.49.01?
-
Yes. What i'm seeing is definitely NOT how it should look like. The bulb should be set to be emissive layer - double sided. And the rectangular lights should be somehow passing trough the bulb(i don't know how - it should be somehow set to transparent or if that's not possible, the lights to be outside the bulb). Nevermind. That's my last problem. When you have time and you're there.. I would like to see what's happening with couple of the copied IES lights, couple of the rectangular lights and couple of the emissive lights. Try also to copy the spotlight object. (not only the lights and the emissive layer). See ya, later. (bow)
-
yes, i am using 1.49.01, see my signature
i asked for your configuration because i thought that the memory insufficiency could cause the problem, but i guess 4GB is just enough. sidenote: while rendering, my task manager shows that sketchup grows to ~1240MB of RAM allocated. i also can understand that saving and reopening the file is even more upsetting in your case, since the 120MB scene takes ages to open...
the second issue i thought of was that maybe just the scene parsing and light cache warming up is taking place (which could be checked by looking at task manager and watching the cpu usage).
but now since there are already two people with the same issue, it's really becoming strange
missing sofa - i honestly didn't notice, i touched no layer settings, i just moved the camera around and copied the spotlight objects (which are shown in Outliner as Vray IES Light).
EDIT: seems that although the sofas showed in SU's viewport, the Layer0 was turned off, and i had to turn it back on so that they are rendered in vray too.editing the chandelier rectangular lights - no crash, edited its color, ran the render... no problems. although i don't think this is how it should look like.

Thanks guys for the help. have not yet solved the problem, but if i do i promise i will put it up on the forum so someone else will not face the same misery

hey, i'm not sure i'm following your instructions correctly, so it would be awesomely helpful, if you recorded your process (with CamStudio for example), put it on youtube and i/we could see, where it crashes for you. try as i may, i'm still not able to reproduce your bug
-
Hi.
I just recorded a short clip that you can see part of my problem. The flick i'm talking about and the lack of rendering. I'm uploading it now. When it's ready i'll post here the link from youtube, so you can all see and try the things.
https://www.youtube.com/watch?v=pMk-0sUoXv8&feature=youtube_gdata_player
If it's not clear again.. I can make more clips so you can see the problem from different angles.

The flickering is coming from V-Ray being done processing the scene and SketchUp window becomes responsive again - where it updates the window. The rendering not starting after it's done processing the scene is probably some bug. I bet if you open the Ruby Console before you hit render you will see error messages appearing.
