Substance Painter Tutorial ? Fundamentals 10: Particle brush


要点まとめ

パーティクルブラシ

SPの目玉機能！として紹介されるパーティクルブラシ！
便利ですが、設定が多くあってちょっとめんどくさいです。




パーティクルブラシの項目

とりあえず、"heavy_leaking"のパーティクルブラシの項目を確認

dt…DistanceTime?パーティクルの間隔を指定してくれるみたいです。

Emitter…エミッターのタイプを設定

SpawnRateFactor…パーティクルの発生量？
SpawnSpeed…パーティクルの発生スピード？
SpawnSpread…パーティクルの拡散量

Receiver…よくわからない。

DrowOnBumpSensityvity…よくわからない
DrowOnGeomSensityvity…よくわからない

FadeOpacity
FadeOpacityRand…のランダマイズ
FadeSize
FadeSizeRand…のランダマイズ
Friction

GlobalWindX…風向き(X方向)
GlobalWindY…風向き(Y方向)
GlobalWindZ…風向き(Z方向)

GravityFactor…重力度

InheritVelocity…法線方向を加味するかどうか。
InheritVelocityRand…上記のランダマイズ

NormalFactor…ノーマルマップへの影響度を指定
ParticleLife…パーティクルの生存時間
ParticleLifeRand…パーティクルの生存時間のランダマイズ
Spread…パーティクルの飛び散り具合?

TurbulencePower…パーティクルの乱れるパワー
TurbulenceScale…パーティクルの乱流のサイズ


ざっとみて赤文字のところが大切そうなところ。
この項目もブラシと同じで、自分でプリセット化が可能。
必要に応じてライブラリ化してね！みたいなかんじです。

Calling Python from Substance Painter

Here is a quick code snippet for calling a Python script from Substance Painter and parsing the results. The in/out is very simple, but serves as an example of using the alg.subprocess.check_output function to bridge the JS api and your own Python scripts. // This can be called from the QML UI, or elsewhere in the plugin code. function GetAllFilesInDirectory(root) { if (root == undefined) return; // I put my scripts in a relative path to keep my plugin tidy. var script_path = "Scripts/FileUtils.py"; // Gathering files var ret = "NOSTRING"; try { // The arguments are used as parameter inputs to the Python script. This requires some planning // and well communicated conventions, but works well enough. ret = alg.subprocess.check_output( [ pypath, // Absolute path to interpreter. script_path, // Relative path to the py script. "log_files_of_type", // sys.argv[1], in this case the python

Python and the Photoshop Script listener

Image
This little guide is written for Photoshop Cs5. Other versions of Photoshop may have slightly different folder setups and listener output locations.  As discussed in a few of my earlier posts, Python is a great choice for scripting in Photoshop when coupled with a good COM interface and a desire to make monkeywork just go away . But as you are busy putting those monkeys to work it is inevitable that you will come up against a command or two that's not made available in the regular Photoshop scripting documents. CRISIS! The monkeys go on strike.  But wait, there is hope! Introducing awesomeness... The scripting listener is a brilliant plugin for Photoshop. Using it gives you access to many commands that are not included in the Photoshop scripting reference. While active (that is, present in the Automate folder) it spits out a JS and VB log of all all your actions in Photoshop. For the purposes of this guide we are only really interested  in the VB log. Getting useful Python code fro

Python Photoshop Automation without win32com- The Example

Image
So here is a working example of what I was talking about in my last blog post- making Photoshop automation possible without needing to use the win32com module. This specific example is not cross-platform compatible. It relies on getting the Photoshop application through it's registry entry, but the subprocess module is cross platform so it shouldn't be too hard to hammer this into a shape that can be used on Mac and PC. Or just Mac. Or whatever. Essentially there is no real magic going on here, just lots of string manipulation behind the scenes. Like I said in my last post, the biggest hole in this right now is the lack of feedback from Photoshop, but that's something I'm looking into when I get a few spare minutes here and there. Here is the example. When you run it, you should come up with something that looks like this: What an Amazing document.  And the code! This is a particularly long snippet. Hang in there! Essentially when the commands are called, like add_new_
