Title: Error loading material from library
Post by: IO3229 on November 01, 2017, 09:31:21 PM
Hi
When attempting to use the "oak leaf" or "maple leaf" presets, I receive the following error message:
Error loading material "_fp_dry_..."" from library "C:\Program Files (x86)\Itoo Software\Forest Pack Pro\matlib\3d_vray.mat"

Only affects these 2 presets. Have reinstalled Forest Pack, and am able to load said library into material editor. Installed all software using defaults. Please advise.

Stand-alone workstation
Windows 10, 64 bit
3ds Max 2016
Vray 3.6
Forest Pack Pro 5.4

Hi,

Big thanks for reporting this problem. Would you mind to double check the Render quality settings for Lawns presets? Having set it to Low, it might affect loading other presets too, even this option isn't available for these. Setting the Render quality (V-Ray/Mental) to High under the Lawns Presets should fix it. We'll check what can be done to avoid this behaviour.

Best regards,

Hello Michal

Many thanks for the prompt reply. Adjusting that setting took care of the issue. Cheers.

Best Regards

Hello

I have a similar error report from my customer. (I am a Japanese reseller)
When loading Meadows of Presets, get the error "3d_vray.mat dosen't exist".
No problem with Lib > 3D libraries.

Changing Render Quality to "High" has no effect.

Use 3dsMax 2019 + V-Ray 3.70 + Forest Pack Pro 6.2.2

Is there any other cause?

Best wishes,

Hi,
Does that file (3d_vray.mat) exist on the corresponding location (C:\Users\<yourUsername>\AppData\Local\Itoo Software\Forest Pack Pro\matlib)?

I would suggest reinstall the problematic packages in the following way from the Update Manager:

If you cannot see installed packages, Go to the View menu and select Installed Packages.
Click on the (i) icon for the package you'd like to remove
From the Details Dialog, click Uninstall.
After it is uninstalled, hit the Install button on the bottom of the Update Manager.

Hope that helps.

Best regards,

hello,Rokas

Thank you for the advice.

3d_vray.mat is present correctly, he has tried reinstalling the library but nothing has changed.
(I passed 3d_vray.mat to the customer from my machine that was working correctly and tried the placement, no effect)

I don't know the cause.

Would You please show us screenshot of the error. Maybe it will help us to identify the issue.
Also, is it the same if You use "Automatic Selector" and explicitly choosing "VRray":
