What is the point of PBR textures if you can’t put them near or under the track where the parallax effect can be seen and appreciated?

As you say, using Trainz 22 SP4 and later on a PC appears to not allow the use of PBR textures near or under the track.

But that’s not the case for Trainz 22 SP4 on a Mac. Sadly, it appears to be the case for Trainz 22 SP5 and Trainz 22 SP6 on a Mac.

Fortunately, I have been able to revert back to Trainz 22 SP4.

In Trainz 22 SP4 you can see the effect of PBR ballast surrounding an unballasted track asset. I spent a couple of months achieving this result over 150 miles of track.

The fact that I have not been able to achieve this result in Trainz 22 SP4 on a PC is the main reason I have not and cannot make my Canadian Pacific Railway Mountain Subdivision route available on the DLS or otherwise, i.e., on my website. Another reason is that the route with High Density (HD) terrain and Physically Based Rending (PBR) is 5.44 GB, much too large to be saved as a CPD file.

I have little hope that N3V will address this issue. I am not even sure they realize it is an issue.

As the Wiki says,

“PBR (Physically Based Rendering) textures have been a part of Trainz since TRS19…”

“PBR Textures do have a few downsides compared to non-PBR textures. Specifically,

They do not mix well with non-PBR textures (including textures used as ballast in track) and, sometimes, with other PBR textures as well. This can cause "height issues" where the two different textures meet. There are techniques that can be used to remove these conflicts.

Sudden (steep) changes in the ground height under a PBR texture can cause an "animation effect" under the texture that has been likened to "wobbling jelly" or moving "jellyfish guts". …”.

“These issues are not unique to Trainz and can be found in all games/sims that use PBR ground textures.”

So, this means it can’t be fixed?

Works in Trainz 22 SP4.

Now that I have Trainz 22 SP4 back I will be sticking to this version until a new version (not an SP update) comes out.

In addition to the jellyfish guts, many if not most PBR textures are over-sized, don't scale well and become more like carpet when used to fill large areas.

Because of this, I turned down shader quality to Basic. This turns off the 3d component in PBR textures and allows them to behave with 2d textures when I have used them for various things such as rocks, sand, and farmland. The other benefit is running with basic shader quality is there's a bit of performance increase and lower temperatures due to less work for the video card.

I have had to turn down shaders to basic also to have all the textures behave and to stop random crashes, even in SP5!

My older laptop struggled until I changed the shaders to basic. I noticed a big difference there and did the same with my desktop even with the much more powerful RTX3080 and I9-12900K

This isn't working for me.

The link I get is a zip file:

https://dl1.n3vgames.com/Installers/TRS22/23Q2/TRS22-Offline-Installer-126273.zip

I've tried replacing the 126273 with both 128487 and 129335.

If you're using the regular retail TRS22 (not Trainz+), then the link would be https://dl1.n3vgames.com/Installers/TRS22/24Q1/TRS22-Offline-Installer-128487.zip

Then just patch using launcher to 129335.
