I finally found time to test Marmoset Toolbag for texturing and I'm quite liking it. Quite easy to get started when you have SP experience, I would even say I prefer it. The carve groups are great. Just missing anchor points to make the texturing more non-destructive. #madewithMarmoset

= Lumik Renderer update = - random walk SSS, with spectral radius, trace sets - got rid of the pixarUSD dependency focusing purely on Gaffer for now. - many performance and bug fixes, but it's been a while so I forgot most of them.

= Lumik Renderer update = - sending render back to Gaffer - LumikOptions node for render settings - few more shaders added - camera parms exported ( e.g. focus distance ) - primvars ! ( that paves way for image textures ) Here testing on one shot from Blender Studio's Sprite Fright short.

= Lumik Renderer update = Continuing with Gaffer integration: - Scene is now sent to the renderer process via TCP instead of reading a file, only deltas are sent. - Shader node connections are exported and implemented in renderer. - Implemented few example shader nodes to show it off.

1/2 Toy renderer update: Started integrating it into Gaffer. For now I managed to register my renderer and some custom shader nodes. When IPR is ran, it saves the scene into a binary file which my renderer keeps checking for updates. Later it should sed deltas via some sockets/TCP.

toy GPU renderer update, mostly focused on better debugging - normal/albedo/debug aovs - AgX on/off - exposure - pixel inspector - saving images to catalogue with settings metadata - poor man's IPR - when the .usd file changes on disk, scene is reloaded - importance sampled HDRI dome lights

To mix up all the CGI nerdiness a bit: Here is an edit of some shots I took on the last two snowkiting trips to Norway. Let the freezing fingers and sketchy gear be the excuse for some of the sloppy photography and color handling. I'll try to do better this year.

Having recently acquired a house to fix and an offspring to raise, I have little time. But I've sneaked in some toy renderer time here and there. Added light MIS, wavelenght importance sampling and really tried improving variance. Battle testing it on scene like this, basically only indirect light.

My fellow EU citizens: we've got work to do and someone made it extremely easy 👏👏👏 For any danes out there, I've made a translation of their basic text, so if you want that please let me know!!

‼ Fight Chat Control - protect EU digital privacy! ‼ The EU may soon mandate scanning private messages and photos, possibly by October. PLEASE, contact your MEPs now - the site has their details (for all EU countries!) and even a message generator to make it easy! https://fightchatcontrol.eu/

Screenshot of https://fightchatcontrol.eu/ The EU (still) wants to scan your private messages and photos The "Chat Control" proposal would mandate scanning of all private digital communications, including encrypted messages and photos. This threatens fundamental privacy rights and digital security for all EU citizens. Currently: 3 member states opposing, 15 member states, 9 member states undecided You Will Be Impacted Every photo, every message, every file you send will be automatically scanned—without your consent or suspicion. This is not about catching criminals. It is mass surveillance imposed on all 450 million citizens of the European Union. Mass Surveillance - Every private message, photo, and file scanned automatically: no suspicion required, no exceptions*, even encrypted communications. Breaking Encryption - Weakening or breaking end-to-end encryption exposes everyone's communications—including sensitive financial, medical, and private data—to hackers, criminals, and hostile actors. Fundamental Rights - Undermines your fundamental rights to privacy and data protection, as guaranteed by Articles 7 and 8 of the EU Charter—rights considered core to European democratic values. False Positives - Automated scanners routinely misidentify innocent content, such as vacation photos or private jokes, as illegal, putting ordinary people at risk of false accusations and damaging investigations. Ineffective Child Protection - Child protection experts and organisations, including the UN, warn that mass surveillance fails to prevent abuse and actually makes children less safe—by weakening security for everyone and diverting resources from proven protective measures. Global Precedent - Creates a dangerous global precedent enabling authoritarian governments, citing EU policy, to roll out intrusive surveillance at home, undermining privacy and free expression worldwide.

In the Future All Food Will Be Cooked in a Microwave, and if You Can’t Deal With That Then You Need to Get Out of the Kitchen

As a restaurant owner – I’m astounded at the rate of progress since microwaves were released a few short years ago. Today’s microwave can cook a frozen burrito. Tomorrow’s m…
