i haven't really been modelling anything lately, i have mostly just been practicing character rigging with ripped game models from models-resource and the more "technical" side of animation/rigging, drivers and such i have some projects in mind though

I have another one: why is uv unwrapping so bad and also why are the tools for rearranging/cleaning uv maps also bad? I unwrap the roundish area around a character's eyes and it becomes weirdly unevenly skewed, and also rotated like 197.4 degrees (i.e. not by some amount that makes sense). Also if it gets any excuse, it will make the uv map overlap.

i think this video came up in my youtube ecommendations when i watched some caustics videos https://www.youtube.com/watch?v=-UjJqwwMJc8 if you use affinity photo, you can get the filmic look with the macros linked in this video while having the option of making adjustments using the full dymamic range: https://www.youtube.com/watch?v=FeTP7WHnQaw and i'm sure that there are options for other software too, but i didn't go looking

yeah, dot product = "sameness" of two vectors. if you use unit vectors, then 1 = the vectors are identical, 0 = the vectors are perpendicular, -1 = the vectors are exactly opposite

i'm pretty sure it is not possible to render a camera in the scene as a texture on... a display screen texture for example. but i guess simulation nodes with their inter-frame dependencies could enabole adding that feature

And here I'm trying to add a butt to my Blender Guru donut: "O" enables proportional editing or you can click on this icon in the viewport  then you can do the edit operation you're doing (here i'm grabbing a single vertex) and it will propagate to the surrounding vertices  then while you're doing the operation, you can use the scrollwheel to change the size of the fallof  if you want to move the vertices along the normal (have the surface "puff up" or "collapse"), use alt-S

or, if you're in sculpt mode, use the grab brush (G) and change its size (F) or strength (shift-F). or possibly the inflate brush (I) and then click to inflate an area of the mesh or ctrl-click to deflate an area. shift-click will smooth the area under the brush

i made it using geometry nodes and drivers here is how the rig looks  to generate the trail, you need to use the good old "x = x0 + v0t + ½at2" formula: first part:  final formula:  then you need points, so here is a mesh line, whose positions are set according to the formula (the t variable is the index of the point from 0 to `trail length`):  then you instance some geometry on the points, but you have to delete all faces so that the preview geometry doesn't emit fluid. the actual emitter is a tiny triangle (radius 0.01) whose normal is aligned toward the fluid target. you can make it bigger if you want and you can add more points, as long as it has at least 1 actual face.  here is the whole node tree  these are the settings in the preview generator's fluid simulation tab. "planar" is set (that's the tiny emitter triangle), "initial velocity" is set, but "source" is 0, and initial X, Y and Z have drivers on them:  the drivers are all basically the same, except the path fopr the input variable is location[1] for the Y coordinate and location[2] for the Z coordinate. i also have a separate multiplier that isn't really needed and you can ignore it.  finally there is the line that goes from the inflow preview generator to the fluid target. it's a mesh with 2 points and an edge between them, lying on the globa Y-axis. it has these constraints on it:  for the animation, i imported this image as a plane  then i traced the strokes adding 4 keyframes on every letter, every 15 frames (so every letter takes 1 second at 60fps). then i looked at where the preview trail intersected the plane every frame and if it deviated too much, i added some an extra keyframe between two existing keyframes. i simulated the fluid and generated the mesh for the fluid. i subdivided the plane so it had "enough" geometry. i made the plane a dynamic paint canvas and i made the fluid a dynamic paint brush. i baked the paintmap and wetmap as vertex colors on the plane and then used them in the shader: wetmap to drive the color and roughness and paintmap as the displacement map.

because i can set the length of the preview trail, i made a Multiple Rounds Simultaneous Impact animation, with fluids. this was kind of a pain in the rear end because i wanted the initial velocity to match the angle of the barrel. i thought i could just make an armature that has a bone for the barrel and child bone that is constrained so it can only move on its local Y-axis. then add a copy location constraint to the generator targeting the tail of the "barrel bone" and another copy location constraint for the target empty, targeting the child bone. it works for the preview generator, but the driver that actually sets the initial velocity of the fluid inside the fluid simulation is evaluated before the constraints so it only dripped the fluid staight down because it didn't see the actual world location of the elements. i ended up adding keyframes for the "visual location" of the generator and target for the 8 frames the inflow is active and that worked. here's the bone setup  and this is the result https://i.imgur.com/rGAXiZt.mp4

i'm trying to figure out how to do bilinear filtering with the blender shader nodes and i cannot wrap my head around it. making a pixelated texture is easy, just use a snap node on the uv. but that makes your textures look like (perspective correct, well lit) playstation textures. but sampling the texture at discrete points and then interpolating between them is too hard for my tiny brain. i know how to do bilinear filtering in java, for example. but wrangling the node graph is such a different paradigm that it gets too complicated too quickly.

i could post the formulas, but here they are: https://en.wikipedia.org/wiki/Bilinear_interpolation  it has this neat graph though.  and yes, with image textures you can resize the images outside bolender and then by default blender uses bilinear filtering when doing texture mapping. but procedural textures have "infinite" resolution. if you're going for a low poly (but not playstation 1) look, both infinitely sharp and perfectly pixelated textures look out of place. one trick is to modifyu the uv with noise. that blurs procedural textures using antialiasing since sub-pixel samples are taken at different uv coordinates. but it looks like poo poo, imo, and is also not deterministic

after making an incorrect implementation and really having a  about it, i figured it outi was inerpolating between snap (current position - 1) and snap (current position + 1), when i should have been inrepolating between snap(current position) and snap(current position + 1) https://i.imgur.com/XpPWSuY.mp4 edit: and the quadratic function: https://i.imgur.com/FjkLWJX.mp4 Wheany fucked around with this message at 11:51 on May 22, 2023 |

i think the index in your case refers to the index of the curve circle. i added a instance on points to your nodes: and in any case, you're selecting in the point domain, but material is set in the face domain, that probably causes some issues

Bluemillion posted:I was trying to get only one face selected with an index value from the circle. well in that case my guess is that you need to select 2 points on the circle and then if you literally want just a single face selected, i guess you need to select some range along the curve, so spline parameter, factor between N and M???
