OctaneRender® 1.024 beta 2.48c TEST (lin/mac/win) [OBSOLETE]

[kubo]

no hassle, the workaround is perfect (2 seconds typing and solved ), thanks for your fast answer, about the render target node, there is no rush, is just one of those things it could come usefull.
Thanks

Yep using Aero on win 7 64 bit

with

1 screen - 24" 1920 x 1200
1 screen - 17" 1280 x 1024

Maybe (if you want) try to disable Aero and open the same applications again and see if the graphics memory still goes down. By the way, what were the apps you opened?

Cheers,
Marcus

Hi

Well this is very interesting.

If you switch off Aero in win7 and load up various programs over octane.The memory barely fluctuates.Not only that but i am now showing 874mb available on the card after powering 2 displays.

The moral of the story.Turn off Aero in win 7. It doesn't half suck up GPU memory.I have gained around 150MB of Video Card Ram by switching it off!

What does min_display_samples do?

It's a feature requested by a technology partner. If you set it to 4, the first displayed image after a change will have at least 4 samples per pixel. Usually you don't need it. It may be useful if you have 2 GTX 590 for example. Then all 4 GPUs can contribite to the very first image displayed, which means it will have only half the noise than the image with 1 sample/pixel.

Marcus

Could you please elaborate on this..
As I do have 4 GPUs, a gtx 590 and two 580s... what happens at the maximum/minimum level, and how does the result look?

Well, try it out and move the camera around You will see what I mean. The visible noise while changing things should be less but the refresh rate goes down, too, if the max_display_samples is higher than the number of GPUs rendering. As I tried to explain before: It only affects the very first render result after a change, i.e. when the rendering restarts.

thanks Jaberwocky! knowing that is going to come handy to my current project since I'm tight in the vram side. Freaking windows sucking resources away

thx for the explanation, so here's what I found out min_display_sample makes rotating and moving super slow on heavy scene when you turn it up , it is more useful at superfast renderable scenes, so it seems to calculate a number of samples and then jumps, which in turn looks like a better renderable scene while rotating - which is ok for superfast renders, but for a slow one do not even attempt as you will notice nothing, it's like reverse from what subsampling does, supersampling? like subscript vs superscript, seems more intuitive to set it to subsampling buttons - if there was more space there
I guess if I have 4 gpus, I set it to 4, as all of them calculate the first frame at the same time, and should get 4 start samples at the same speed as when starting from sample 1 - when moving around the scene. I guess it makes a difference if you have more gpus, maybe when nvidia starts poping out like 8 core graphic cards, and I get 4 of those i set it at 32 ..

So when you set it at a number, it calculates the samples to the number you have set and then makes the rotate/pan/zoom action - and I thought it's another magical slider that makes the render scene look more pretty

Sorry i meant the component names do not appear on the render vewport using the material eyedropper.
They do if you hover the cursor over the scene node pins , just not if you hover the materials eye dropper over the viewport.

Octane never did that, did it? Did that work in the past?

Thanks,
Marcus

well it did for me in the last Beta unless i'm going crazy

sorry yes i am going crazy ignore that.I mean when you just hover the cursor over the render preview screen you should get the part names up that the cursor arrow is hovering over , just like you do on the nodes in the node screen.

Not having a good day here.

Marcus

Sorry , my report above was wrong.The Preview render pop ups are working.I was using the l.h.mouse button.I should have been using the r.h.mouse button....OOOPs!!!!

2 small details (mini bugs), not 2.48 specific, they are more a keep in mind type of thing. When launched on command line, if there is a spelling error on the output filepath the image won't be saved, could it be done that the render be saved in the project folder or the needed folders be created in those cases?, and the second thing is that when a floattexture is added to the roughness value of a glossy materials it doesn't have the necessary precision to be useful .
Thanks
(all this comes cause I screwed last nights renders output path and found out this morning that Octane did it's job but didn't save it , it's totally my fault, but since already Octane usually knows better than me, why not add another FOOL-proof feature, )

could it be done that the render be saved in the project folder or the needed folders be created in those cases

In the past, I asked if we could have a specific render folder in the preferences, in order to separate input files and output files... It would be really usefull, because if you don't set manually a path for each saved image, the project folder is poluted by tons of rendered images. It is tedious !

Hm, with the Softimage plugin you can choose a different output folder for the images.
I wonder me, if the other can´t...
