Im trying to render in cycles, everyting elese looks fine but the models that are emission texture comes out weird, any idea why this is happening??
That looks like a de-noising issue. Try turning off de-noising and see how that works.
Or failing that, try turning up the quality of the glare node.
Try intel denoise. The vanilla one can cause fireflies to go haywire.
I would also use area lights for the actual lighting here, relying on emission only for camera. Lighting with many emission meshes is usually a no-go for me.
