Hi, in this file two methods: in vex and without one. The point attribute @dist is a distance to the next point. distance.hipnc

Hi, look at this topic

Or you can load a texture with Display Options

In file two versions - geo_v1 and geo_v2. Try it, maybe this is what you are looking for Recursivetest_01.hipnc

Maybe I can't completely understand what you are trying to achieve. I did simple test: created float attribute before for-each loop equal 100.0 , at each iteration took a square root and added it to result of previous iteration. It works as expected, it accumulate values of attribute at each step, I've got 110, 120.488, 131.465, 142.931, 154.886... and so on. I did not use solver sop at all.

Hi, is an income value of attribute not changing through the loop iteration, isn't it? If so, why not just to add incoming attribute at each iteration? RecursiveSolver_01.hipnc

Hi, i know two ways to make it works, it may be more though: 1. Inside Animation Editor there is "Function" drop down menu at the bottom of the window. Select segment of animation curve and choose "linear()" 2. Inside Parameter tab - toggle animated parameter with LMB and you can see function type of animation curve ("bezier()" by default). You can set time slider between two keyframes and in field of animated parameter type "linear()". This change type of animation curve on segment between two keyframes.

Try this expression: `opname("..")` Edit: No, it"s wrong, this expression does not work in this field Edit_2: This is one of possible solutions: https://www.sidefx.com/docs/houdini17.5/hom/locations.html#node_event_files You should create folder "sop" in your "$HOUDINI_USER_PREF_DIR/scripts" directory, and "object_merge_OnCreated.py" file in that folder: n = kwargs["node"] parent_name = n.parent().name() n.setName(parent_name, unique_name=True) This will be rename object merge node on creation with name of it parent object node. Disadvantage is that each new object merge node will be rename. Maybe there is more convenient way, i don't know.

Hi, yes it's possible

Hi, go to menu Assets, then Asset Manager (or RMB on an asset in Network View -> Show in Asset Manager), tab Configuration, drop down menu "Asset Bar"

Hi, yes it's possible. You can use value of attributes from SOP. See simple example i attached. I've animated parameters Enable and Color of Light object. Click RMB on parameter Enable: Expression -> Edit Expression and you can see an expression. You can use CHOP for this also. light_control.hipnc

Hi Evan, maybe this tutorial helps you

Hi, increase Reytracing Bias parameter in Shading tab of Mantra ROP, something to 0.01. Don't ask me why, i only know what the help says.

Hi, if you want two side material with bumped metal on one side and glossy plastic on the other, i presume it is the best choice to use bump instead of displacement, because displacement has influence to all geometry. Here two pictures: first with displacement, second with bump. Principled shader does not have ability to use noise for bump by default. You can change a shader and use "noise displacement bump" tab to control bump. See hip. 2Sided_01.hipnc
