Finally I got it but I have also a DR problem

[bardo]

Dear bdancer,
finally we updated our 3dsmax license to the 3.0 and now I can use Vray4Blender... I hope i'll be able to use it in production substituing 3dsmax, at the moment I'm studying how to convert my models library and how vray4blender works.

One of these tests was done to check if DR works but I've got just black renders.
Just to clear, the slaves work fine as 3dsmax render slaves.

Here my installation process.

Render slaves
I've installed the 3dsmax 3.00.05 setup file and choosen the "render slave" option.

Workstation
Installed the 3dsmax psetup file as "workstation"

Downloaded from your nightly build page the latest build.
Started Vray4Blender, if I press "render" with default settings it works regular.

Ok, after I've tested the DR.


First of all, in every render slaves, I created a desktop shortcut to the vray.exe command ( the path is "C:\Program Files\Chaos Group\V-Ray\RT for 3ds Max 2014 for x64\bin") with this command options C:\Windows\system32\cmd.exe /kvray.exe -server -portNumber=20204

Then I've run the shortcut

Then start Vray4Blender in the worksation, enabled DR.
In the DR section, I've added the ip of slaves, set a shared network directory (it's a network mapped drive).
I've saved the scene in the same shared directory.

I've started the render but the rendered image is completly black.
The communication from workstation to the slaves seems fine because when the render starts, the slaves react loading the scene.

I've noted that if I use the "Auto transfer" option, the workstation buckets work but the render slaves not (black buckets).

Where am I wrong?

Just another question: support posts like this, should go the "bugs" section or where? In 3dsmax section there is a "problem" section, it's the same purpose of the "bugs" one?

Thanks in advance.

[bardo]

Solved... I did a mistake: I've downloaded the sable version instead of the dev one.

Now with dev, DR works.

At the moment I can't use the NodeTree, I hope to find how to use it.

[bardo]

bdancer,
to have the node shading editor, I have to follow the instructions in this page https://github.com/bdancer/vb30/wiki ?

I've tied to use it but it doesn't work.

Or are there another ways?

[bdancer]

bardo, you could try downloading build with -vb30- in name - it already contrains all needed stuff for vb30.

[bardo]

Thank you bdancer, I've downloaded and it's ok...

Now I'm going to study....

Just for info, is it already implemented a "rendered viewport" option as Cycles can do?

[bdancer]

Rendered viewport is not yet possible =(

[andybot_cg]

no nodes yet in this build tho? Do you have any working nodes builds with 2.70?

[bardo]

yes..the nodes with the latest nightly build is ok.

[andybot_cg]

I tried the vb30 dev build, but for some reason nodes that I created in blender 2.69 are not showing up. Here is my error:

Traceback (most recent call last):
File "C:\Program Files\VRayBlender-2.70\2.70\scripts\startup\bl_ui\space_node.py", line 84, in draw
layout.prop(snode_id.render, "use_free_unused_nodes", text="Free Unused")
AttributeError: 'Material' object has no attribute 'render'

location: <unknown location>:-1

This is what my nodes window looks like in 2.69 (working) versus 2.70 (not working)
My 2.69 dev build is from 2014-02-14 Hash: 3bd9986

Any ideas??

[bdancer]

Well it looks like vb30 addon was not loaded. Check the top of the log.

[andybot_cg]

Not sure what's wrong. I tried already moving the vb30 folder to startup and addons, but neither place gives me nodes. It exports the scene and renders fine, it's only my material nodes that aren't showing up (and I'm getting just default white materials in my render). It looks like it's operating effectively as vb25 only.

[bdancer]

Well you could only have one exporter activated vb25 or vb30. If you have vb30 in "scripts/addons" and vb25 in "scripts/startup" then remove vb25 or move it "scripts/addons".

[andybot_cg]

I had another install of vb 2.70, I installed this latest dev build in a program files folder with a different name. Once I deleted all 2.70 installs and reinstalled it's working now. It must have been reading the startup file from the other folder. Odd, because I don't seem to have had problems installing multiple versions before. Maybe it's a Windows cache thing.

Now that it's running tho, I am getting quite a few errors, so I'll start a new thread with info on that.
