DR problem.............

[aurelarchi]

Hi to all !!

I just bought Corona last week in FairSaaS one year license.
All is perfect good job guys !!
But i have trouble with the DR mode.
In fact when i use it the render become more and more darker.
The slaves starting render and working well on the passes. (DR corona started as administrator )
For information all the slaves have the same gamma and have access to the network files, in vray DR all working well.

Sorry for my English.......... ;)

Hi,

-Did you activate Corona on all render nodes?
-If it is possible, can you start 3ds Max on each render node and see if it is able to successfully render locally?
-Are all the render nodes able to reach the texture files? Paths are configured properly?

Maybe you will find a solution here:

update:
-Are you using the same version of DrServer on all render nodes and master? (same as Corona)
-Are you using some plugin for textures or lighting?

update2:
-check "retain EXRs" in DR render settings on master pc and check the files after rendering (hold your mouse on the "retain..." checkbox to see where they will be saved)

sorry for being so undecided. :)

Hi Maru !

Thanks for the quick answer !
I used the same installer to install Corona on the workstation and on the slaves.
Yes i used the license.exe in the corona file to activate it with my mail and my password on slaves, but maybe it's not the good way.
I can't run max on the slave to test it because i have only one max license.
No plug for textures lighting and the path for textures is ok and properly made.

Thx !

hi,
in that case try the "retain EXRs" option - it will help a lot with pinpointing the issue

[aurelarchi]

OK, i will try this option tomorrow !

Thanks a lot !

I have the same issue with DR. I've installed the 45 day demo versión to try it out and everything works flawlessly except for DR. Everytime data is received from render nodes the image starts to get brighter and brighter.
I tried with vray converted scenes and this happens every time, tried with a very simple scene from scratch with corona and rendered fine though. I have decided to buy the box license because I think this renderer is way better than vray but I would like to solve this problem first since I don't know if it is something I'm doing wrong or a bug inside corona

I have the same issue with DR.

Are you using some other plugins than Corona in this scene? For example vray hdri loader or some texture generating plugin? Something related to textures/maps/lights?

[aurelarchi]

In my case, no HDRI just corona sun+sky, for the textures i used multi textures, but like in a other post i updates the version to the 2.0 in all machines.
I will try this morning to update the local data file on the slave or to run max and activate Corona.

Update : When i run max on a slave Corona is fully activated.

[aurelarchi]

Ok, please check this tests images, the first one is when only workstation started and image two when the 2 render slaves are in.
In this case i just used texture for the floor no multi textures.

Thx !

Update : Same gamma in all machines, no problems with vray DR

[maru]

Wait, you said that the image is getting darker, now it looks like it's getting brighter. Is this another issue?
To me this looks like missing texture (only diffuse color is showing) or gamma problem.
Can you perform this:
-check "retain EXRs" in DR render settings on master pc and check the files after rendering (hold your mouse on the "retain..." checkbox to see where they will be saved)

[aurelarchi]

Yes strange, with multi texture image become more and more darker and with simple texture more and more brighter.
I think is a missing textures issu.
But all my slave have the right and acces on my NAS, for example same texture link in max with vray and no problem.
I will try the "retains EXR's.

Thx !

[maru]

Ok. There is also this:
https://forum.corona-renderer.com/index.php/topic,7208.0.html
But I don't understand what he did to fix this. I sent him a message.

[aurelarchi]

Ok, gamma checked on all the slave, no prob is ok.
I tested DR with a white mat scene, ok too.
So the problem come from a missing texture file on the NAS. The wood one.
But, all the slave have access on it and the Asset Tracking Dialog is ok, link are ok too.
Strange.................Tested the same scene on vray DR, all is ok.

I recieved an answer from user CHampi22 who had similar problem:

I used Auslogics Bootspeed -> Tweak Manager tools - System security option to disable the User Accesss Control ,all security option OFF and compelte access for anonymous user in Privacy policy.
This is the only way to access textures,  otherwise TCP 1977 port error in DR server, I don't Know why.

Maybe this will help?

[aurelarchi]

" Auslogics Bootspeed" ?

Strange software to resolve missing map or map link......................
I'm actually testing the same scene, with the same texture link on vray DR, working well.
When i switch on Corona i got the same issu.
Strange isn't it ?
