试着弄个蚂蚱路径,分了三段让它跳{:4_173:} 制作漂亮。赞! 现在的歌词很精准了啊 蚂蚱会三级跳,厉害哈 歌词同步的微调很到位,太赞了
亲爱的,这个歌词同步颜色修改的漂亮{:4_199:} {:4_199:} 两只蝴蝶的颜色搭配的真好,给整个画面增添了生气。 加林森 发表于 2022-9-21 21:38
制作漂亮。赞!
谢谢队长鼓励,这个也是套用呢{:4_173:} 绿叶清舟 发表于 2022-9-21 21:38
现在的歌词很精准了啊
黑黑弄了个新的微调制作帖子,到那里面就能做出更准确的歌词了{:4_173:} 马黑黑 发表于 2022-9-21 21:45
蚂蚱会三级跳,厉害哈
我实在吃不准T的效果,弄了3个Q的效果,好在是45度方向的取值,仍然可以平分各段,若是其他角度就比较难分了。{:4_173:} 马黑黑 发表于 2022-9-21 21:46
歌词同步的微调很到位,太赞了
应该谢谢黑黑的那个微调帖子,那个取到小数点后一位的设计太准确了{:4_187:} 小辣椒 发表于 2022-9-21 21:49
亲爱的,这个歌词同步颜色修改的漂亮
歌词颜色就是黑黑原来的,我直接套用的,唯一花点心思的是那只蚂蚱的路径{:4_173:} 醉美水芙蓉 发表于 2022-9-22 07:00
红影厉害做得更漂亮!
谢谢水芙蓉美女鼓励{:4_187:} 梦油 发表于 2022-9-22 09:14
两只蝴蝶的颜色搭配的真好,给整个画面增添了生气。
那俩小蝴蝶是以前上传的,就直接拿来用了{:4_173:} 红影 发表于 2022-9-22 10:51
应该谢谢黑黑的那个微调帖子,那个取到小数点后一位的设计太准确了
也要手巧的才行 红影 发表于 2022-9-22 10:51

曲线的线外控制点是关键吧 马黑黑 发表于 2022-9-22 12:11
曲线的线外控制点是关键吧
噩梦,线外控制点决定了曲线的凸起是多点还是少点。这点仍然可以均匀分布,让三段是相似的。
