SDK P3Dv4.4 Modeling Tools for Max 2012_x64

[lagaffe]

Hi,

After 6 month working on my least scenery about Mirabel with the SDK 4.3.29.25520 I have decided to upgrade to P3Dv4.4 (Prepar3D_v4_SDK_Setup_4.4.16.27106).
The SDK installation was fine and ConfigSDK.Exe was run as Administrator to finish these install.

So I will to create a PBRTexture from the Material Editor and at each try I obtain a plugin handler exception "-- Unknown property:"g_BrdfLutTexture" in (null):DirectX_Shader". In background, Maxscript open the file: SDK_P3Dv4\Modeling\3ds Max\Common\Scripts\Startup\PBRMaterial.ms at line 460.

Is Max 2012 x64 still really supported? Do you have some solution?

Did you also update the Prepar3D client and content to v4.4? There are new PBR textures included in the content installer.

Thanks

Hi,
I proceed with a full uninstall of v4.3, and after that client, content and scenery of the v4.4 were installed on a empty directory: S:\P3D
The version of the SDK has also changed since the 28 Nov: first I find the ***077 and Saturday I can download the **106 revision ... very strange, doesn't it ? No information find about this modification on this forum, or I cann't find it.

In each case, I uninstalled the last SDK, install the new one and apply ConfigSDK.exe with Administrator rights and success.

I can create a Prepar3D texture but when I try PBRTexture ... I have this execption.

Best regards.

Nobody use Max2012 - x64 and has intented to install this SDK ?

I believe the issue is with Max 2012. It's so old it probably doesn't know anything about PBR. I believe the current minimum supported version of Max is 2014.

Thanks for your answer WarpD,

But this SDK provided 3DSM2012 (32 bits) 3DSM2012 (54 bits) 3DSM2014 (64 bits) 3DSM2015 (64 bits) 3DSM2017 (64 bits) and 3DSM2018 (64 bits) so the 3DSM2012 (64 bits) should be working ...

It is a limitation of 3DS Max. Directx shaders were limited to DirectX9 in older version of max. Our PBR shader requires DirectX11. We still ship the legacy plugins to support legacy content, but we can't guarantee every new feature works on all versions. Also, for software no longer provided or support by its author, we may not be able to obtain new licenses to test with. We understand there is a substantial financial impact to updating, and we do our best to support legacy versions to the extent that we can.

Thanks

I use 3ds Max 2019 and have the very same problem as the OP. Max pops open a max script error related to DirectX shader when ever I select a PBR material. The same error occurs for MSFS 2020 materials. It seems to be a DirectX problem but I am at a loss as to where to search. Any suggestions?
