OctaneRender™ for Blender 1.20.1 - 1.1 beta [OBSOLETE]

[aLeXXtoR]

Hi!
I found something weird - I have a mesh which is quite heavy. Cycles gave up the attempt to render (run out of memory - gtx590 2x 1.5GB). But Octane renders it without problems. The weird thing is that it shows mem peak ~1680M after finishing rendering.
Unluckily today I am going with my family on vacation (1 week) and come back to test it when I return.

Did you use both cards with Cycles?


I'm not quite sure (Jim would correct me), but it seems that Octane spreads data between memories of all used cards.

Another Bug:
When I use a "Octane Specular Node" for the windows glass (Materialname "Fen_Glas") and turning on "Fake Shadows" it happens sometimes that Fake Shadows do not render correct, they render like "Fake Shadows" is turned off.

See here (Fake Shadows turned on in Material Node):

Then I have to turn off "Fake Shadows" and it renders correct.
See here (Fake Shadows turned off in the Material Node):

When I turn on "Fake Shadows" again then it still renders correct, see here:

Edit:
Sometimes this happens when I change Values of other Material, for example when I change the Roughness Value of the Floor material.

Kind regards
Alain

The following seems to be a Bug too.

In some cases "Render Region" does render only a part of the selected region, see here:

Did not find out yet when this happens.

Edit:
And when I render with F12 then it renders something completely wrong, see comparison here:

Kind regards

Render Region seems to be just a fake !

Render Region:

Then hitting the Pause Button.
Then unchecking "Render Region".
Then you see this:

What? Who have told you at all that the "region render" feature is available in the plugin, to let you name it "the fake"? It is just "setting the borders" feature which I've coded in the integration for your convenience despite the fact the Octane engine does not support regions at all.
Have you read the announce thread?

I can disable borders support, if you don't like it - all for your pleasure.

Hi Marten74, I am not sure I understand all what you ask.
This is a plane unwrapped from view, right is 3dview shading (Material), left is render.

Hello, and thank you for your answer!

Some images in this post to explain my issues a bit better.

Here you can see my problem with projecting a square that adopts the resolution of the image. I I hit ctrl + P it´s a perfect match. Not sure if it has to do with an image beeing "pre loaded" in to the texture slot, but I never had this behaviour working in the regular Blender. For some reason for the other two examples/images I got the uv-mapping working the way it should. I did not by accident use "project from view (bounds)" that would have given a similar result. The surface would have covered the whole image then though. Not sure what it is that gives the first strange projection result...

In the other two images you can see that for the texture emission the UV mapping is not working correctly. As you also can see I have tried to figure out a way using nodes to get this right. The problem is that I don´t have time to sit a bunch of hours to figure this out, so I´m hoping some one with more experience can see if I´m simply doing it wrong, or if there is a little glitch some where in the plugin.

You can also see that I don´t see the texture in regular shading mode. I have also tried to apply the texture in the texture panel, even if this should not be nessesary. This problem made me realise that the shading options in the display menue in the properties panel are missing. For you this seems to work the way it should.

I have a computer with a GTX Titan. I wonder if it can have something to do with that since the BlenderOctane is not the latest Blender release and I know that support for the Titan has been added pretty late, maybe after the first 2.68 release.

Thanks again for your post, looking forward to the next answer

Hi, could you post the blend with packed textures?
Are you able to get it in Octane standalone?

Hello!

I´m in a tight project right now and when I finish I will be away from keyboard for a while. Will post a scene when I´m back in a week or so. I did stuff I did not save in the scene I took screen shots from, so it will take a bit of time to get it "in shape", and I also have to strip it down a bit since there are some stuff in it I should not share.

I have no problems what so ever in the stand alone version when I export with Yoyoz export script.

Thanks for shown interest in by "problems". I might still be the biggest one

Cheers

Sorry, I did not see that post. Please understand that I cannot read through hundrets of posts for every little question
I suggest to turn that feature off because for now it's a deception and useless.

But I think that the feature should stay - it's pretty handy.

And for me it is natural to seek the answers yourself before asking them. I mean in this case one should read through the posts or use search function instead of writing a "bug report" immediately. Or we all would be drowning in flood. ))
