SSL: CERTIFICATE_VERIFY_FAILED certificate verify failed Dec. 16, 2021, 5:12 p.m.

Hello hello,

For reasons I won't go into I am stuck running houdini on a Macbook for a while and while loading up one my files, where I am using TOPs and specifically the "Download File" TOPs node.

in OSX I can't run this anymore due to the following error:

ERROR: <urlopen error certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)>

Error running Python callback 'onCookTask':

URLError: <urlopen error certificate verify failed: unable to get local issuer certificate (_ssl.c:1076)>

I have python 3 (3.10) installed and have run the certificate install there, which completed.

Also have to note, all this works perfectly fine without issues on Windows.

I'm not quite sure what Houdini wants and how I fix it, so anyone seen this before?

Thank you

BUG: XPU does not render TGA texture files Oct. 31, 2021, 8:48 a.m.

I am listing this as a bug since, yes TGA is maybe used less these days, it is still a very valid format and older assets use them.

Anyway XPU completely fails and just renders black when a TGA file is used as a texture. As soon as I convert it to say jpeg, everything renders correctly.
