Hello.
I'm running Substance 2018.3 on Windows 10 with drivers NVIDIA 436.48. When I open large files, it opens in the program, and then, not having time to load, the Painter crashes.
I captured a video: https://youtu.be/z5H8qp3_h-M
I note that specifically with this scene and with this system (Windows, GPU, CPU, RAM) there was no such problem before.
Same problem when opening the same file in 2019.2.1.
I emphasize that the problem is not specifically with this file, but with any large file.
The system has an automatic swap file if there is not enough RAM.
I read this topic - https://support.allegorithmic.com/documentation/display/SPDOC/Software+conflicts , but I do not have such software

Update: if part of the RAM is occupied (I opened a browser with many tabs and the Garri's mod), then the painter almost freezes and no longer consumes memory.

any suggestions would be greatly appreciated!  :)

Substance PainterSubstance Painter - Technical Support - Custom shader
 on: February 24, 2017, 01:36:25 am 
Hi guys! I studied all the documentation about shader in Substance Painter and in the end it did not work :(
I need to convert roughness map to smoothness map by the formula (1-0.7r)^3, where r - Roughness map. I have modified default shader pbr-metal-rough but it did not work. All I managed to do - is create new channel user0 and for some reason it is written basecolor map, but in code i set noway basecolor.

//: param auto channel_user0
uniform sampler2D user0_tex;


And I have a formula:

user0 = pow(1.0 - 0.7 * roughness, 3);

This syntax is true. It seems to me that the problem is in the definition of the new channel. Can you help me, please?
P.S. Sorry, English is not my first language

Substance PainterSubstance Painter - Technical Support - Create user channel

Hi. Tell me, please, can I somehow use these User channel for create and exporting textures? I need to convert a roughness map to smoothness according to the formula (1-0,7R) ^ 3 (R - roughness) and I want to use this channel User0 and then export User0. This is done by editing the shader or how?

Hi. Tell me, please, can I somehow use these custom slots for exporting textures?
I need to convert a roughness map to smoothness according to the formula (1-0,7r) ^ 3. At the moment, for this purpose, I use Substance Designer, but it is inconvenient
1. Can I use these slots?
2. How I can use these slots?
In the "Export" section of the documentation is not told about it
