Error that occurs intermittently in a specific function.

[KOVIAHN]

hello.

I understand that the function below creates a new Material.

void CUnigineMaterialManager::Set_Object_Material_Property(Unigine::ObjectPtr object,
	OBJECT_MATERIAL_MASK changeMask,
	Unigine::Math::vec4 property,
	int iSurface
)
{
	return;
	switch (changeMask)
	{
	case OBJECT_MATERIAL_MASK::METALNESS:
		object->setMaterialParameterFloat4("metalness", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::ROUGHNESS:
		object->setMaterialParameterFloat4("roughness", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::ALBEDO_COLOR:
		object->setMaterialParameterFloat4("albedo_color", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::UV_TRANSFORM:
		object->setMaterialParameterFloat4("uv_transform", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::MIRROR_ROTATION:
		object->setMaterialParameterFloat4("reflection_pivot_rotation", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::EMMISIVECOLOR:
		object->setMaterialParameterFloat4("emission_color", property, iSurface);
		break;
	case OBJECT_MATERIAL_MASK::AUXILIARYCOLOR:
		object->setMaterialParameterFloat4("auxiliary_color", Unigine::Math::vec4(1.0f, 0.0f, 0.0f, 0.5f), iSurface);
		break;
	}
}

However, after creating a new Material, Assertion Fail is displayed, and then an error occurs in Unigine_x64d.dll!Engine::iterate().

The reason this is difficult to solve is that it doesn't always happen.
If I comment out the above code, the problem does not occur.

I'm not sure how to approach it.
I am attaching the place where the error occurred, so please tell me when the error occurred.

thank you

Have you tried to check if material parameter or even surface id are really exists in this object?

Based only on this small sample code it would be hard to guess what's going on here. If you can replicate this issue on a very simplified test project with only part of your content (or even synthetic cubes) - it would be great. That will allow us to find the root cause of this issue much faster.

Thanks!

Dear silent

I am  analyzing the cause of the termination by referring to the unallocated object (an object that has actually been created but has never been rendered).

I hope this can be fixed, but I'll try to get back to you if the problem reoccurs.

Thank you very much!

Great, thanks :)
