Description:
Using SEUS Shaders and preview_OptiFine_1.12.2_HD_U_D3_pre the Chunk Borders are not shown

You mean F9? That is actually Minecraft code. All DS does it turn it on/off.

i'll try and upload some images, yes the thing that says [Dynamic Surroundings] Chunk Border Display ON/OFF

at certain angles the border lines appear, and most times they dont

The MoreOverlays mod works ok - prefer everything in one mod like DS

all i did was look up for image 33 and move forward for image 40

Understand. But my point is that it is Minecraft that is doing the rendering, not Dynamic Surroundings. The chunk border fencing is a debug tool built into Minecraft. All DS does is turn the fencing on/off at a keypress.

fair enough

could you make a better rendering version tho?

In this particular case I think SEUS should be compatible with Minecraft fencing. As for coming up with a better version than what Minecraft does I have been thinking of this off and on. Main challenge for me is what would make my fencing better than the one Minecraft has (besides SEUS compatibility).

well I got 4 arguments for it

1. It keeps it all in 1 mod
2. It would be Shaders Compatible
3. It seems in keeping with the mod
4. You could link in with FTB and show different colours for claimed areas/loaded areas

but of course it depends on how difficult it is to write the code etc

just a thought
