Want dynamic shadows in a baked environment?

Keep baked lighting in the distance.

Enable dynamic shadows only near the camera.

A good balance between performance and visual quality.

Happy to officially rejoin the Unreal Authorized Instructor program for 2026!

A few years ago I was teaching Unreal Engine in classrooms across Paris.
Today I’m sharing real production workflows online from Tokyo.

The place changed, but my passion for teaching didn’t.

Want large scenes to run on mobile?

Use a Cull Distance Volume.

• Cover your entire scene
• Set distances based on object size

Less objects rendered.
Better performance.

Unreal Engine Tip #05

Your mobile build is too big?

Fix it:
• Max Texture Size
• Only needed maps
• Lightmap resolution

Smaller build. Better performance.

One tree might be fine on mobile…
But a forest?

Foliage can quickly become expensive.

The fix:
• Fewer, larger leaves
• Leaf clusters instead of single leaves
• Simpler branches

Same look. Much lighter.

Unreal Engine 30-Second Tip 02

Baked lighting makes foliage shadows static.

The fix:

• Cast Dynamic Shadow on foliage
• Use a Stationary light
• Adjust shadow distance

A good balance between performance and visual quality.

Unreal Engine tip

Getting “Video Memory Has Been Exhausted”?

The culprit might be your textures.

Quick fix:
• Pack channels (RMA)
• Reduce to 512px

Result:
94 MB → 710 KB (~99% VRAM saved)

Cinematic UE5 environment → mobile.

Porting a scene built for high-end rendering to mobile
required optimizing several parts of the pipeline.

Here’s a quick breakdown of some of the main optimizations I implemented for Nihon Legacy

Recreating a real Japanese heritage place in Unreal Engine 5.

My new project ! I recreated the Meiji-jingu shrine from Tokyo in Unreal Engine 5.4.

The modeling was made from scratch using reference pictures that I took at the Meiji-jingu shrine.
