Improve your scenes performance with a single click!

Draw Call Optimizer allows you to drastically reduce the amount of draw calls used in your scene and heavily increase your FPS without losing a lot of visual quality. This is done by combining multiple techniques like mesh combining and texture atlas mapping.

This tool was built because of the lack of tools out there which are easy to use and powerful at the same time.

- one-click solution (which can be modified but does not need to).

- supports texture repeat and offset

- supports mip-maps correctly

- supports the Standard shader (parallax, emission, diffuse, normal, specular, cutout, etc; without details)

- supports many mobile and legacy shaders

- supports all shader fields due to dynamic evaluation

- requires no lightmap UV recomputation (super-fast lightmap UV re-layouting)

- Automatically fixes missing lightmap UVs

- respects your colliders and merges them as well including simple colliders (boxes, capsules, …)

- fully supports classic render pipeline

- input textures and materials stay untouched (your project assets won’t be modified)

- NEW: Supports creation of multiple atlas maps for a single material

- Contains tools for image scaling and channel manipulation

- Keep your components on your optimized hierarchy

- Merge meshes larger than 64k vertices

- Configure your atlas mapping strategy, size, margin

- Discard texture channels during optimization

- Option to just run atlas map creation without combining meshes

- Contains source code

- Can be used as a package instead of being inside of your code

- Tested with Unity 2020.3 and higher

- Contains source code

- Includes 3D Collider Utility 2 - Merge and Combine

- BETA: URP and HDRP are supported as well but atlas shader graphs need to be adapted by hand (you need to replace texture samplers by a sub-graph (provided))

- BETA: Create atlas shaders automatically for your (simple) custom shaders.

Works on Desktop and Mobile.
