[URP] Optimize objects that use the same material with different values.

[LianZH]

Hi all,

I have a bunch of game objects that share the same material. During run-time, each game object will change color or fade individually. What are the best approaches with minimal overhead?

Currently, each object is using a different material instance, so the draw call count is huge. I did some research and found “Instanced property” and “Per Renderer Data”. Is it the correct approach to use them to minimize the draw call count?

Learn how to use MaterialPropertyBlocks and [PerRendererData] for great performance gains!

Hey there! I found that while MaterialPropertyBlocks are very useful, the documentation on them is sparse at best. I’ve come to use them quite often, so I’ve decided to write about them in the hope that someone will find the information of use. You can read the article on my blog, right here. Spoiler: 15 milliseconds are shaved off of rendering time in my sample scene. Have fun animating materials the efficient way!

I found out this can solve my issue. Not sure if there are better methods.

Did this work for you? I was just reading about these and the docs say it will reduce performance in URP and HDRP and it isn’t compatible with static batcher?
