Alfred 慢慢的需要鞭策時

我的Alfred設定好像有問題,目前job都會慢吞吞的在跑, 手動需要按RETRY才會跑的比較快

目前同事有個暫時的解法, 在cmd理找出alfred的PID編號

ps aux| grep alfred

然後打STRACE 的指令 (例, 20069, alfred 的pid)

strace -p 20069

有時候strace也會卡住,就點一下CMD畫面

renderman shader裡加 custom aov layer

新的AllPurpose Shader 裡開個" Incandescence" shading component, intensity set to 0, color attach a Color Slbox
slbox 寫法請參考以下圖檔

結果會是final render不會出現, 但是會出現在aov的圖層裏面

two sided shader in renderman

如果遇到正反面是不同屬性的材質，可以用SLBOX來寫condition,利用model的face normal來判斷.
sl code寫法如下,v1跟v2可再各自串聯node上去

/* color */
if ((dPdu^dPdv).N>0)
result = v1;
else
result = v2;


記得maya model的double side 要關掉，renderman的ensemble的double shaded 要開
