Hi, I'm hoping someone can help me figure this out.... While texturing a model using procedural metallic shaders I created, I've somehow made it so that when rendered with the Superfly render engine, some sparkly things show up on the model. I don't know what they are or how to be rid of them. It has something to do with my render settings I'm sure but what it is, I don't know. Please see the images showing the rendered pic, my silver metallic shader node setup and my render settings. Any help is appreciated - thanks

Superfly/Cycles/PBR: reflection and spec do the same thing. You don't want both being used in the same mat. I'd say just log on to shareCG and download my free PBR shader for Superfly https://sharecg.com/v/86231/gallery/7/Material-and-Shader/Poser-11-Superfly-Uber-Shader-version-3 Uber Shader 3.jpg

Just to address the original problem: The sparkles are called "fireflys" and they are (IIRC) the render engine struggling to render highlights from very small lights. Point lights will do this as will small, bright area lights and small mesh lights. You would want to use bigger lights, or light your scene some other way like use a skydome with an image texture to light the whole scene (like in my render above)

For simple metal effects the physical root node can be used and only requires two parameters to be adjusted. Set metal to 1 and adjust roughness to suit, 0 will give mirror reflection so probably want it slightly higher. Optionally, colour can be adjusted via diffuse node. Don't change the spec node, the metal and roughness settings will automatically set the correct highlights. Unless you want pits in the armour surface I'd modulate any grain effect from the roughness node.

Reduce the bump settings a bit. Use Area lights. ( I realise you are using the processor's graphics capabilites and not a graphics accelerator card to render your scene).
