Hi,

It does look like an aliasing artifact.

You can further reduce aliasing by applying additional anti-aliasing using the Antialiaser or TX Antialiaser GW modules.
If you are working with a Render_General compound, these modules are already included in it. Simply open the Render_General compound using the Edit Compound In-Place option and enable these modules:

This is not what I need. I watched this, the result is not good. How to export this correctly with blender

Hi,

Could you please share the model, preferably including its textures? It's difficult to gather much information from just that single image.

Otherwise, enabling the Wireframe view on the shader's model might help you identify any irregularities in the model's geometry:

Additionally, you could import the model into a basic scene, such as [Common]:Compounds\Scene\Default_3D_Scene.xcomp, using a simple material to observe how it behaves.

Warmest regards,

Where should I send you the model?

Hi,

You can send it to sales@aximmetry.com and refer to this forum post in the email.

Warmest regards,

Sent!

Hi,

The TX Antialiaser GW module fixed the aliasing for us, without it:

With TX Antialiaser:

Note that TX Antialiaser GW's Velocity Map should be connected to the Camera's Velocity Map video pin:

Another issue is that the model is incorrect and it cannot be triangulated correctly. As you can see in the image above the bottom object is not the same as it was in Blender.
You should adjust the topology so the glow parts are not made up of ngons. Here is a possible solution(top) compared to the original(bottom):
