This is the code I’m using. And yes I know I’m created the same material twice. I’m just doing this as a test. 2nd material will be entered once I get this working.

function init(self)
	-- Store references to the materials
	self.material1 = hash("/assets/rainbow/rainbow.materialc")
	self.material2 = hash("/assets/rainbow/rainbow.materialc")
	--self.material2 = resource.load("/assets/materials/holographic/holographic.materialc")
end

function on_message(self, message_id, message, sender)
	if message_id == hash("change_shader") then
		if message.shader == 1 then
			go.set("#sprite", "material", self.material1)
		elseif message.shader == 2 then
			go.set("#sprite", "material", self.material2)
		end
		-- ... handle more shaders as needed
	end
end

Error code -10 means RESOURCE_NOT_FOUND. In this case, I’m guessing rainbow.materialc isn’t referenced anywhere so it’s not included in the build. The simplest way to fix that is to use go.property() with resource.material():

go.property("material1", resource.material("/assets/rainbow/rainbow.materialc"))

It should be throwing a proper error message instead of crashing the engine though :thinking:

Agree. @schlista could you please create a ticket on GH?

done.

How change material on generated GO with 2 sprites (SOLVED)

Thanks for the work around. Here’s a related question. Any idea why I have to put a c on the end of material when I’m hashing it?

I noticed as I worked with shaders the console will add a c to the material name.

See this works around the issue as you suggested. But I had to use go.property without the c on the end of material. If I add it it doesn’t run and makes me use .material before it will run. And if I delete the c on these it crashes defold.

self.material1 = hash("/assets/rainbow/rainbow.materialc")
self.material2 = hash("/assets/rainbow/rainbow.materialc")

This is the work around code:

function init(self)
	-- Store references to the materials
	go.property("material1", resource.material("/assets/rainbow/rainbow.material"))
	
	self.material1 = hash("/assets/rainbow/rainbow.materialc")
	self.material2 = hash("/assets/rainbow/rainbow.materialc")
	--self.material2 = resource.load("/assets/materials/holographic/holographic.materialc")
end

All files get a c at the end when compiling (short for “compiled” I guess?).

My bad, Defold adds a c automatically when it’s a a property of a component.

You can skip the hash part by setting it up like in the resource.material() doc:

go.property("my_material", resource.material("/material.material"))
function init(self)
  go.set("#sprite", "material", self.my_material)
end

Correct, the compiled versions of files get a c at the end. And by compiled we mean going from text based protobuf format to binary and doing whatever kind of transformation that might be needed on the resource (Lua source to bytecode for instance, or uncompressed to compressed textures).
