TRS2019 build 100240
When viewing a Transdem map with ortho textures in surveyor the map has a strange appearance. this has been discussed in the Trainz forum here https://forums.auran.com/trainz/showthr ... -the-scene
I tried this Using trs19.
Create a new map with one baseboard.
Paint the whole with one transdem128 texture.
Zoom out till you have a 3d view and rotate the camera on the painted ground, changing the viewing angles till you see a strong torchlight effect shining on the surface.
Now rotate the texture painting direction 90 degrees and paint a small area.
Repeat this at 90 degrees and you will see the textures light up in different lights at different angles. Increase the height in different places and see the effect.
Now paint the whole with a different non Transdem texture and the effect will disappear and become normal.
I realize that this is not the way these ground textures should be used, but it does show that something is not right.
I guess the reason for this is that that the TD textures are completely non 3D flat and this reflects the sun?? making the torchlight effect.
I have been experimenting using a normal map as a bump map from another texture which solves(I think) the problem. (Having no previous experience with graphics, I have been doing a crash course in texture making to work all this out about normal maps, bump maps, and texture.text files
Hope I make myself understood with this as I really think that this problem should be solved if Transdem and ortho textures are to be is used in TRS19.
