GPU Instancer Pro:FAQ

General Questions

What are the Minimum Requirements?

---

To provide the fastest possible performance, GPU Instancer Pro utilizes indirect GPU instancing using Unity's RenderMeshInstanced API and Compute Shaders. The target devices should support GPU instancing (SystemInfo.supportsInstancing) and Compute Shaders (SystemInfo.supportsComputeShaders).

Please also note that even though some integrated graphics cards may satisfy these requirements, they may not provide the boost you can get from GPU Instancing. Therefore, hardware with a dedicated GPU is recommended.

What are the Known Limitations?

---

There are certain limitations that are introduced by the way Indirect GPU instancing works and/or how Unity handles it. Below you can find a list of the known limitations.

Lighting Limitations:

• Baked Global Illumination is not supported for instanced prototypes (baked lighting data will be ignored for GPUI instances, but you can use it for the rest of the scene objects)

• Light Probes are not supported (all the instances share the same probe value).

• Ray Tracing is not supported.

Shader Limitations:

• Geometry shaders are not supported.

• Tesselation shaders are not supported

Android Limitations:

• It requires special care to decide what you can render when targeting Android Devices. Android platforms have inherent GPU limitations and target devices must both support GPU instancing and fare good with it. For example the amount of objects possible to render would be lower than a desktop platform - where the maximum number of instances and prototypes might vary depending on the devices' GPU limitations. Therefore, you must make sure that the number of prototypes and instances per those prototypes do not exceed the target devices' GPU limitations.

Miscellaneous Limitations:

• Negative scaling on GameObjects is not supported.
• Occlusion culling feature is not supported when using HDRP Dynamic Resolution.
