I’ve understood I need to use the compositor to add the glare effect. But it’s not clear what to do when working with animation. I need the effect from frame 800 to 850, and I’ve already rendered the frames. What do I do? (if you could please explain step by step. Thanks.)
In the compositor I’ve set an Image layer node, selected the image sequence option, and then the frame 800. But although I’ve applied the glare node, the View animation (in the render tab) won’t show any glare.
You can open a new “VFX” blender file (File>>New>>VFX), to render frames 800 to 850 with glare into a separate folder.
In the new file, go to the compositor tab, check on “Use Nodes”, delete “Render Layers” node
Add an “Image Sequence” node. Select just frames 1 to 850. Change the “Start Frame” on the image sequence node to 800.
change your scene settings to 800 to 850, and pixels, ratio to match original.
Create a “Viewer” node (output node to see edit). Plug the image sequence into both Composite and Viewer nodes.
Create a glare node, change from streaks (if you want) to Fog Glow. Connect from Image Sequence to Glare, then from Glare to View and Composite nodes. Lower the Threshold if needed (so it affects darker and darker values). Change “Size” if needed, etc.
You should be able to render it out into a separate folder. You could’ve grabbed just frames 800-850 at the beginning, but not sure if you’d need to rename all those frames, since it should render what the current scene settings say for frame name/number.
it’s rendering, but no glare
Is it at least showing anything in the compositing window? Is your scene really dark? It should be set up something like this, except different frame settings…
You could lower threshold, duplicate the glare node a few times, see if anything shows. Also by off chance, make sure compositing is checked on in the Output Properties tab>>Post Processing. Beyond that, not sure.
