When I make glass cup object, I notice there is alot of white dots on my glass cup's reflection like this (For your info, this is in render view mode) enter image description here

Since then, I try this tips https://www.blenderguru.com/articles/7-ways-get-rid-fireflies, start by set clamp direct and indirect to 50 and set seed to 1, set bounces : max = 32, diffuse = 4, glossy = 32, transmission = 32, set glossy filter by 0.5 to set up this nodes. enter image description here

How to get rid of this white dots? Here is the blend file https://pasteall.org/blend/a0e8344abc3d466d85e0f289b1cfd71c

  • I'm not sure you can avoid that if you've already tried all the recommendation for fireflies, the sampling is high (1000), the more you'll wait (while Blender is calculating) the less you'll see these fireflies, see: https://zupimages.net/up/22/16/8cb4.jpg – moonboots Apr 21 '22 at 07:33
  • @moonboots is that object of mine? cause it has many light on its reflection – Earvin Williams Apr 21 '22 at 07:37
  • it's yours................ – moonboots Apr 21 '22 at 07:38
  • i wonder how to make object's shade smooth unlike in my picture. Is it because the light or something? – Earvin Williams Apr 21 '22 at 07:50
  • as we can see at the top left of your 3D view, you are just at the beginning of the calculation (Path Tracing Sample 5/1000), so there are still fireflies, you need to wait until it reaches a higher sampling to see the fireflies disappear. As for the the shade smooth of your picture, could you please highlight what you're refering to? – moonboots Apr 21 '22 at 08:04
  • Oh sorry for confusing you, what i mean is "shadow" not " shade", i want to know how i can make my object's shadow into one single smooth shadow, not just like many of black dots like in my picture and the one picture you give me – Earvin Williams Apr 21 '22 at 11:42
  • do you mean make the shadow more transparent? If I'm not wrong I think there's a problem with glass shadows in both Eevee and Cycles (although caustics should be soon fixed if I remember correctly), but there are tricks to have something more transparent if it interests you: https://blenderartists.org/t/glass-surfaces-are-treated-as-opaque-by-shadow-rays/702554 – moonboots Apr 21 '22 at 11:52
