I'm using a custom renderer for a block that is mouldable into different shapes(pillars, stairs, small blocks, etc...) and I was wondering if there is a setting that after the information has been updated to "cache" or make minecraft remember how the block looked with the result of the render so I dont have to do all the checks on each pass which block model to render.

 

The reason I ask this is that on my potato pc the normal world seems to render smoothly, but as soon as my custom block comes into view it kinda turns a bit choppy if I move the camera a lot.(10fps pc yay) and I can see the world behind it rendering first and then the block I made. I do not have those issue with standard blocks.

 

Any help or tips are greatly appriciated.

That is what I first tried, but the limitations of that dont allow me to render exactly what I want to render and how I want to render it. I will have to use  TESR for what I want, because the object is in "fluid" movement at the moment of change, but when the morphing process is over it just remains stable and doesnt need updates.

 

I'm just trying to keep low end pc's in mind heh. Is there somewhere in forge a display list I can tap into to insert my information? I cant use a display list in my code becase then the block doesnt render in the hotbar.

Use a ISBRH and just tell the game that the block needs re-rendering.
