Houdini 19 Mapbox not functioning 2023年5月17日20:18

i am glad i found this thread! FYI you cant use a tablet when using the little window to find your area, it throws nan errors. you must use a mouse. although i failed to have my edits work.
(after installing mercantile) here are my edits
5 import mercantile
125 #terrain_url = " []" + str(lon) +"," + str(lat) + "," + str((zoom+1)) + "/1024x1024@2x.png?access_token=" + API_KEY
126 #fixed code
127 x, y, z = mercantile.tile(lon, lat, zoom)
128 terrain_url = f" []{z}/{x}/{y},512@2x.pngraw?access_token={API_KEY}"

this is the error, when i find my location and press download...

When I render with Karma output is spamming about Redshift 2023年3月14日10:24

The redshift plug-in loading and licensing adds about 25 seconds to each frame I render with karma. When your frame is 2 seconds and the redshift crap is 25 it kinda ruins the party. I am keen for any ideas or workarounds.

Time shifting payloads later 2023年3月1日16:50

So I am making a set of explosions with a volume, frame by frame changing spark geometry and point instanced chunks. I have made the proxy geometry for each of the 3 elements and made 9 different versions of the explosion.

I am trying to make an asset that can be placed down have its variants switched on its 3 elements and be time shifted. I have vdb’s for the pyro and usd’s for all the other elements. I have made a version that can variant switch and be duplicated. As for time shifting that isn’t working as I expected. I am trying to write the asset to disk and re load it in with mixed results. There will be 1-5 explosions per shot used so it is ok to be a bit inefficient.

How can I time offset it. How should I structure it?
