Low-poly 3D Models for PlayCanvas

PlayCanvas loads GLB as a container asset: drop a FoliMesh file into the Editor — FBX is converted on import — and you get a template with the whole model hierarchy, or call app.assets.loadFromUrl(url, 'container') with asset.resource.instantiateRenderEntity() in engine-only code.

The engine has no LOD component, so a short script compares camera distance and toggles the render components of the LOD0–LOD3 entities; static trees can share a batch group, and large forests use meshInstance.setInstancing() with a vertex buffer of transforms. Flat shading and vertex colours mean no textures and no UV work, so an Oak, a Saguaro or a Bush from the 42-model set shares one material that multiplies by vertex colour. Budgets of a few hundred to a couple of thousand triangles at LOD0 suit mobile WebGL, VR and stylised strategy or city-builder games.

About the Low-poly style

Low-poly vegetation is the cheapest style to render and to ship.

Flat shading: one normal per face gives the crisp faceted look; no normal maps.
Colour lives in vertex colours (glTF COLOR_0), so there are no textures, no UV work and almost no video memory.
Leaves are solid geometry, not alpha cards: no alpha testing and no transparent overdraw, which matters on mobile GPUs.
One material can be shared by every model in the scene, so trees batch and instance easily.
Typical budgets range from a few hundred to a couple of thousand triangles at LOD0.

A good fit for mobile, WebGL/WebGPU, VR, strategy, city builders and stylised indie games. In the engine, use a material that multiplies by vertex colour.

Using it in PlayCanvas

PlayCanvas treats GLB as a container asset. In the Editor, upload GLB (FBX is converted to GLB on import) to get a template with the model hierarchy; in engine-only code use app.assets.loadFromUrl(url, 'container') and asset.resource.instantiateRenderEntity().

LOD: there is no built-in LOD component, so a small script compares camera distance and toggles the render components of the LOD0–LOD3 entities.
Static trees can share a batch group to merge draw calls; for large forests use hardware instancing with meshInstance.setInstancing() and a vertex buffer of transforms.
Leaves: glTF MASK sets alphaTest on the StandardMaterial; use cull mode none for two-sided leaves.
Collision mesh: a collision component of type mesh plus a static rigidbody, with its render component disabled.
