Күн бұрын

I owe a tutorial video for the updates made for Blender 4.2 that eliminate the Floating Point Error issues for lensing. If you have questions reach me on Instagram or X at @jackimorphic Inspiration for this fix came from ‪@AlaskanFX‬ using the Ray Portal Feature.
Thanks for watching!

Bought it on gumroad but it doesn't have the 4.2 update, only the old version. Can you please update gumroad product?

@@LeonhardEuler-d4k If you check now, it should be updated ! let me know if it din't go through! I tend to forget about the Gumroad page since its not as popular as the blender market one... sorry about that! if you email me i cna send you a code to have access to the Blender Market one

Super cool man! Did you build it with node groups or using osl? I’ve been working with Zircron45 on lens simulation for a bit, finished my own set of lenses made with actual geometry right before the ray portal node got released and been trying to do some lens simulations with it since

@JackToth Ай бұрын

I started making them with blender 3.2 way back so had to do physical geometry since ray shaders werent native yet, see my channel for the og vids, the physical geometry when scaled properly absolutely has to stay static to mitigate floating point errors, if you want some additional lenses i can email you a download code. Do you want to affiliate for my kits possibly??

Thanks for this starter tutorial - I thought it would be a lot more complicated but now I feel I can do some simple renders to test out the lens. I'm just starting with your lens kits and this is super helpful! Can I ask which vintage lenses your anamorphic lens where modelled after? I went on a wild goose chase for old lens patent schematic drawings and I couldn't find any decent info for my holy grail anamorphics (Panavision C Series). One more thing, if you could please explain the difference between the single focus and dual focus jackimorphics and when to use which, that would be much appreciated, also. Thanks Jack!

Yea! Do you have an email i can send something to? I also browsed HEAVILY for some of the famous ones but they are too protected. I ended up using my own simplified formulas which bring some heavy spherical aberrations in the original singlefocus/dualfocus versions. I also came up with an original prescription for the WIDE2x. The SHARP models use a different approach i can send in email

Very interesting, I'm not a photographer or filmmaker so don't really know about lenses. But you seem to explain things very well. Why would one use these lenses instead of the built in camera? And can the built in not do these effects?

@JackToth Ай бұрын

Oh man camera guys (photographers, cinematographers) can get incredibly detailed about the characteristics of lens choice for a shot/photo. The depth of field from a lens is probably one of the most important behind flaring and other obvious ends. Lately I've noticed more and more modern movies being shot with vintage glass sets that bring alot of effects not found in blender stock cameras nor accurately recreated with the 'aperture' trick, so recreating some of the most popular vintage lenses seemed like a perfect solution. This way the rays are bending nearly perfect to that of the lens they are based on and makes a big difference to the image

Hello Jack , I bought on the blender market for the 4.2 update , but i noticed a white line when rendering my scene with the jackimorphic camera.

@JackToth 5 күн бұрын

The camera is physicaly placed at the (0,0,0) location and portals rays to the rig, i think your scene (maybe the floor or something else) is clipping into the blackbox and being seen by the rig, Can you move the rest of your scene upwards maybe a few meters in Z?

@@danielsery5083 its gotta be in that location to mitigate the floating point errors that were previously present. There may be a way to just boolean an object if you find it clipping into the camera box! Like a floor or such
