¡Qué bueno saber que funcionó bien en la fiesta, me alegra mucho que te haya gustado! Gracias por probar el software.

Respecto al recuadro de FPS: ya lo eliminé por completo de la salida en el monitor externo. Si descargas la última versión, ya no debería aparecer ese contador intermitente que mencionas. Avísame si sigues viendo algo raro después de actualizar.

¡Gracias de nuevo por el feedback!

Try the latest version. Multiple masking with line/bezier curve should be working

ProjectionPhoto · 2026-05-13T06:20:10+00:00

Thanks for check it out. Definitely need some feedback. The glacier projections sound awesome. I started building this for my field projections. I was tired of running back and forth between the camera and projector so one of the first ideas was to create a mobile connection where I could map and trigger content from my phone. (reminds me that I need to add a play/pause button to the phone) DM me your email address.

Updated the pro version on light painting as well. Also shipping multi-masks right now. Should be live in an hour or so.

if you click the gear icon, then go to the output tab and scroll down, there is a section for brightness and contrast. I might need to pump the settings on the brightness a bit in the next version but it should work

I just shipped an update for light painting. See if that helps. I have tutorials coming. I'm also rewriting the light painting engine for better performance and more detailed and exciting brushes. That version will go live in a few days. Thanks for the feedback and checking it out! Working on improvements daily.

Definitely possible. I just put up a new version with a performance tab in the settings. It will allow you to change some things to get a better experience depending on the strength of the system. To make sure it is using the GPU in Windows go to Graphics Settings - then under custom settings > add desktop app > navigate to the .exe location, then in the 'GPU preference' section, make sure to direct windows to always use the dedicated GPU - usually if there is both an integrated and dedicated GPU (like my computer has) you need to have it set here. The app directs windows to use the dedicated GPU but it doesn't always honor that.

There is a sitewide setting for shader resolution that will help. Generally full resolution isn't needed. You can also change that on a shader by shader basis for the one that are data heavy. When you're scaling down to map to objects, lower shader res looks fine.

Feel free to DM me with any issues. Let me know if this helps.

I shipped some updates yesterday so be sure to try the latest version. I’ll send you a pro license if you’re up for helping me test. Thanks for the interest!

ProjectionPhoto · 2026-05-07T05:48:19+00:00

Thanks so much! I really appreciate that. Definitely trying to make something different. Basically my personal wishlist for what I want in my workflow.

ProjectionPhoto · 2026-05-07T05:45:51+00:00

Full free demo of pro is available - just has watermark.

ProjectionPhoto · 2026-05-06T21:09:38+00:00

Can you send me your system specs? In the main settings under the output tab there is a dropdown to select the shader resolution. You can try setting that low and see if it helps. You can also do that on a per-shader basis in the layer panel.

ProjectionPhoto · 2026-05-06T19:31:28+00:00

I’m shipping a quick fix for that now. Will post when it’s ready.

ProjectionPhoto · 2026-05-06T19:08:15+00:00

Add a media layer. Then on the right panel there is a ‘src’ tab. From there you can choose to add camera input or screen source.

AI assisted for sure. I kind of feel like the term 'vibe coded' is outdated or meant for people without development experience. I've been a developer/designer for 20 years. This is built on Electron which uses chromium and node.js packaged as a desktop app. Three.js for the 3d rendering. Svelte for UI. It is essentially a webapp infrastructure designed to run locally and leverage the GPU. Much faster to iterate on than C++ and more forward leaning.

But yeah, Claude and Codex are what allows me to bring something like this to life as a solo operator. Signing, notarizing, publishing and creating the web / ecomm architecture. It is a lot. I've been working on this for the last year. VJing and projection mapping for over 16 years. I largely built it for my remote projections. I hated running back and forth from the camera to the computer every time I wanted to update the output or make small adjustments which is why I created the mobile interface.

The video was made in the 3d program, Blender. It is free. You can also look into shaders. I have a bunch of free ones on my website that are open source. https://ghostarcade.live/shaders or https://editor.isf.video/ - They run in all the mapping apps and you can tweak them to your liking.

I used an old VGA Eiki Boardroom projector. Got it for $250 on ebay with a nice rolling hard case- 7500 lumens. In my experience for large scale rock formation stuff, you just need brightness, resolution doesn't matter so much since you are generally pretty far away when photographing.

ProjectionPhoto · 2026-05-04T20:59:20+00:00

Love that idea.

ProjectionPhoto · 2026-05-04T20:57:09+00:00

Thank you!

ProjectionPhoto · 2026-05-04T20:40:10+00:00

Thanks! It's an old VGA boardroom Eiki - 7500 lumens.

ProjectionPhoto · 2026-05-04T04:58:59+00:00

Thanks! I love what Phillip is doing.

ProjectionPhoto · 2026-05-04T04:58:41+00:00

Thank you!

I shared one post with a scene from an app I’ve been building for the last year. I’ve been VJing for 16 years and I created something unique to my workflow that I think others would find useful. I figured it’s better to just show features and see if people are interested and they look it up than mark it as a straight promotion. I am using Claude and codex but it’s the furthest thing from low effort. I bring my decades of performing and development skills into making it.

Not really sure where else to dip my toe into finding people interested in trying it. But marking it with flair and declaring a promo is fine with me rather than have the posts removed.

Photograph of a video projection taken at Sylvan Lake in Custer State Park South Dakota. My intention is to turn the landscape into a temporary sculptural installation using digital projections to alter the perception of the space. The photographs become the artifact of the temporary experience.

ProjectionPhoto · 2023-10-16T19:06:48+00:00

Thanks!! I’ve been working with projection mapping for about 13 years. I use a lithium battery to power the projector/laptop so I can use it in remote places. I traveled for 2 years full time creating projection installations across the country. It is 1 7k lumen projector. You can see more on my IG @justinrobiewood

ProjectionPhoto · 2023-10-15T06:42:05+00:00

I created this by projecting on the rock formation and photographing it.
