Whenever I try to render in like 8000x6000, sometimes even smaller (like 5000x3000) or something like that, I get error messages...

Tried to render smaller areas but not much success. Isnt a way to render directly to a file?

Does rendering multiple channels (diffuse, alpha, etc) overburdens the memory thus creating the error?

I'm guessing that your computer is running out of RAM, if you want to avoid this you need to render directly to vrimage, this can be found in the output drop down menu, and you are going to want to select .exr as the save type.

the downside of this is that vfb channels are not stored or saved but I think are still processed annoyingly (someone might have to correct me on that) but generally yes using the extra channels will slow your render down.

thanks for the reply valero, what I'm looking for is kind of bespoke so if I gotta pay I gotta pay, will be absorbed within the fee, using google images for free is too risky what with copyright and what not

Hi guys

probably not really applicable to this forum but I need to get some stock images to populate my scenes, I have found trees and people etc but am looking for something more niche ie a reed bed to go next to a lake, does anyone know any good sites to purchase image stocks such as these? I have had no luck google searching.

Thanks

unfortunately, exr only saves diffuse and alpha channels. For additional channels, you would have to render to vrimage and convert to individual exr files.

Hi andybot

and thanks, its not that I want exr, its just that exr you can get in huge sizes without crashing the machine, now that I'm becoming more adept with vray, I figure export the RGB as .exr at large format, then export vfb channels normally turning off the the RGB values and possibly turning the quality down to achieve the right size, still I havent tested it..

ah thanks man, I wasnt sure whether it was an in render feature or post production or even what it was called, now I know!

Still you have to be careful you dont get carried away with too much post production!

thanks guys

it looks like 'bloom' is the right terminology for what I'm looking for, I've found this tutorial
to do it manually,

http://backgroundremovetutorials.wordpress.com/2011/06/07/creating-bloom-effect-in-photoshop/

although it will affect the whole image, if I select the right vfb channels there is probably a way to isolate it to the areas I want.

Thanks

Yeh not quite what I was after but worth saving for later,

Thanks anyways!

Does V-ray have bloom options?

Not as far as I know??? but someone better qualified might be able to answer, I'm happy to do it as a post production effect but have no idea how to do it!

Hi guys

I've asked alot of questions recently so my apologies but heres another, does anyone know how to get that glow effect when the sun strikes a particular object? I suspect its post production but either way I'd like to know. this is someone elses but you can see how the white areas that catch the sun glow

Hi guys

I'm not sure whats causing it but I am trying to load a number of photo textures (31 in total) each around 50 kb each so quite small, there are already a number of textures that are in my model, I removed the larger ones that were not being used but the sketchup keeps crashing after I add say 10 of 30 files im trying to add, whats causing this? the file is not particularly big but I do also have vray installed as well.

Hi guys

Learning lots at the moment and the ole render to exr image is a life safer meaning my computer can handle complex scenes without crashing, but so far when i render to exr the vfb channels are lost, is there a way to bring these back, or would I have to render them normally then enlarge via photoshop to match the exr?

Dont load VISOPTS - if you are using a different version than the vispot was created with, you will have a lot of issues. There were major changes in the 1.05 to 1.49 versions. Just click the reset defaults on the options panel and try that. I think its the visopts that are your issue.

Valero Point taken, a few of my renders were running (ie going through the motions) but not actually doing the rendering, then when setting up the scene manually with exact same settings it was running fine, seems like vray is actually quite buggy and we're really at the front end of it as a piece of software

The quickest way to get an existing site into your reflections is to take several shots with your digital camera, stitch them together in Photoshop, then create an arched plane in SU behind the camera and map the image onto it so that it will appear in your reflections.

Hey Valero

when you put it onto the plane how do you get the scale correct? can you position the texture at all?

Hi guys thanks for your replys, I am probably going to go down this route because I'm more confident with this method that any other ie messing around with GI lighting, shadows as well as physical camera on or off. I'll let you know how I get on. Thanks!

Hi guys thanks for the advice, I removed the emissive materials, loaded multiple different visopt settings and got the same result, I've accepted that that model is not recoverable so I copied and pasted it into the archived model which initially gave me problems because the DR spawner couldnt find the materials, I ended up packaging them and reimporting them and restarting the sortware and its working fine now.

just for the record I've attached a small sample, the top left hand corner should be sky whilst the rest is a timber rainscreen fixed back to a dark material. It does look over exposed but what was causing it I dont know, I'm not a pro by any means with Vray and I know the smallest tick box can have the greatest effect, one thing that could be responsible is that I followed the settings for having environmental light whilst retaining sketchup sun shadows using the reflection glitch, although all the settings were returned to normal, I have a feeling it might have had something to do with that

Hi Andy bot,

I'm not 100% it is a material, I've got no idea really but I've loaded and reloaded various visopt's with the same results, I think I'm just going to revert to an older archived model but it would be nice to find out what the cause is.

I remember in another model it was fine and then I brought in a material from the vray standards a chrome I think and for some reason it ruined all the glass in the scene, in the end I had to use a different material and I have a suspicion the same thing has happened here.

Hi Guys

Unfortunately I can't attach an image due to the nature of the work but I have a model and scene that has been rendering perfectly fine until today, I've tweaked a few materials (updated a few jpeg materials and added an emissive material) now when I click render the whole image is bleached, including the sky which is now white, I've tried loading lots of different kinds of visopts but the results still the same, what gone wrong? I'm guessing something within a material because this is the only thing I have changed and as I mentioned different visopt's are yielding the same results

Oh also I've opened an older version of the same model and this is fine so I can't work out whats ruined it?

few additional points...

GI and BG are set to the sunlight plugin with default settings

physical camera is on and set to more or less defaults

Ok Cheers

i'm guessing you've watched that vid, is there any reason why he turns the physical camera off? would this still work?

Chon

Thanks for the speedy response, it seems like quite along work around but at least I get to learn more about the software!

Do you know if this works as well for bitmaps and if not why not?

Thanks!
